FOREWORD

Wood anatomical atlases with photographs and descriptions of woods of different species are publications that are useful for many years. Atlases published in the 1930's are still used in the 1990's, and will continue to be valuable referencesfor years to come. This publication is in the tradition of such atlases. In the 1990's there is an appreciation and a concern for con­ serving biodiversity, with particular emphasis on tropical forests. Proper utilization of wood and avoiding waste might be considered part of a conservation strategy. This book with its identification key to the woods of the major timber trees of Guyana is a contribution to such a strategy. The first step in the proper utilization of a wood is knowing what species it is, so that it will be correctly processed and an end-use appropriate for its properties will be cho­ sen.

Hand lens keys are useful not only for professional wood scientists, but for anyone with a curiosity or need to know the identity of a piece of wood. The audience for hand lens keys includes not only professional wood scientists, but anyone, including carpenters and crafts­ men. Hand lens identification does not require expensive equipment, but a good eye, and some attention to detail. Even though it is at times necessary to use microscopic features of woodfor identification, when dealing with a limited number of species from a limited geo­ graphic area, macroscopic features, those features easily seen with a hand lens, often are sufficient for wood identification. Hand lens identification might be considered "low tech" because sample preparation is so easy. When this "low tech" approach is combined with the ready access to computers that now exists the result is an "improved" identification process, as computer-aided wood identification programs and databases speed the process of com­ parison. This work provides a detailed introductionto features useful for hand lens identifi­ cation, and a useful computerized key for woods of the . It is a thoughtfully con­ structed work that will benefit a wide audience. As many of the woods included in the key occur outside of Guyana, it is usefulfor anyone with an interest in woods from Central and South America.

7 8 1 INTRODUCTION

The tropical rain forests are still being destroyed over immense areas by fire deforestation, felling and through road-building. The danger to the environment and the burden this de­ struction places upon it are comparable to the thinning of the ozone layer, the on-going exterminationof diverse species of animal and plant life, and the insidious contamination of air, water and earth with chemicals. The widespread, common awareness of these problems in industrial nations is not more than two decades old. The problem of environmental de­ struction, on the other hand, is as old as civilization itself. Seemingly though, only tribal groups of indigenous people have been able to live in harmony with their environment by pursuing a natural sustainable growingcycle. The flowers of the Greek and Roman cultures, by contrast, were responsible for vast felling and climatical changes within the Mediterra­ nean basin. The awareness of environmental problems - and, above all, the implementation of the necessary changes - have three prerequisites: peace, prosperity and insight. Armed conflicts this century clearly show that wars are ruthless vis-a-vis the environment, whether natural or cultural. Environmental problems are pushed aside wherever they infringe on the fulfilment of elementary needs such as food, clothing or housing, as is the case in many developing tropical countries. And finally, specialized knowledge is essential to successfully tackle the analysis of complex problems, and in order to find solutions to them.

The endangered tropicalrain forests cannotbe effectively protected with any single measure. While Forest Service, laws, satellite supervision and international conferences all have a part to play, more is needed. The prerequisites of peace, prosperity and insight must be striven for. fu order to achieve these aims it is above all necessary to check the self-interest of the individual and that of nations; that of the former through society and of the latter through international organizations. We have to learn to share with others who are less fortunate. It is important that the value of the rain forests is raised in the estimation of the people of the countries concerned: one does not destroy that which one values highly. This, however, has to include an environmentally friendly use of the forest. If one starts to ques­ tion all changes, one ends up by questioning civilization itself, as each school, hospital, road and railway built also means the loss of a piece of nature. fudeed, nature itself can be said to be in a state of "dynamic balance" which takes changes into account, such as the change fromegg-laying dinosaursto mammals 70 million years ago. fu the same way, changes in the rain forestscannot be excluded. But the senseless destruction of the rain forestsmust stop in order to ensure their ultimate survival. This can only be achieved by applying fitting solu­ tions to the problem and by a differentiated management system of the forest. A long-term and nature-friendly policy must be implemented which takes both the needs of a sustainable forest plantation and the legitimate needs of peopled reservations into account. The goal is clearly defined, the way is long, and time is running out. This book is a modest contribution to attaining that goal.

The project that led to this book was developed in 1989 within the framework of a multi­ disciplinary research initiative of the TropenbosFoundation. fu the summer of that year, Mr. Ben J.H. ter Welle, then co-ordinator of Tropenbos Guyana, approached various research institutes, of which the Swiss Federal fustitute of Technology in Ztirich was one, with the proposal of sharing the administration of the project. After preliminary discussions and negotiations at the beginning of 1990, Prof. Dr. Hans Heinrich Bosshard, who at the time held the Chair of Wood Science and Wood Technology, agreed to undertake the part of the project labelled A 2.2. Prof. Dr. Ladislav J. Kucera was entrusted with working out a con­ cept and led the project through all its phases. The definitive (i.e. already identified) sam­ ples were made available by Tropenbos (collection Marcel Polak); some additional samples

9 were supplied by Dr. Regis B. Miller, Madison, Wisconsin, U. S.A., as well as from our own Xylothek.

In a first step, Mrs. Teresa Geisinger tested ways and means of obtaining an optimal cross section cut; boiling and cutting with a special knife proved to be the better method as op­ posedto sanding. In years of painstaking work she also prepared all the samples. Mrs. Alice Hirzel was responsiblefor the macro pictures and carried out all the photographical work in the dark room. She also further developed our macro picture technique. The actual descrip­ tion of macroscopic features was the basis of an ETH diploma thesis from Mr. Matthias Brunner in 1992. An innovative part of this work was the development, together with Mr. Otmar Baumann, of a computer software programme for wood identification. Even though the diploma work was well done and well received, the head of the project decided on im­ provements and additions, which were consequently carried out by Mr. Matthias Brunner and Dr. ErnstZil.rcher. Many useful suggestions came fromDr. Livia Bergamin Strotz and a former colleague, Dr. Karel Bonsen, who actively supported the project at the beginning. The maps were drawn by Mr. HR. Rypkema from the information collected by Dr. Marcel Polak, both of theHerbarium Division, University of Utrecht. Mrs.Ursula Stockermade up a meticulous register and Mrs. Angela Rast took care of the English translation. The authors wish to thank the above-mentioned people for their work and also those who - like Mrs. Stephane Croptier - helped in testing the software, in collecting additional information from literature and in checking the data of the camera-ready manuscript. They also wish to thank all others who helped the project along with advice and suggestions, especially Mr. Frederic Beaud for the design of the synoptic tables. The execution of the project was financedfrom the funds of the Chair of Wood Science of the Swiss Federal Institute of Technology in Zil.rich, except the maps with the geographic distribution of the species and the printing of the camera-ready manuscript.

This book serves as a handy tool in the identification of 115 of the most important wood species in Guyana. At the same time, it contains a lot of information on the geographical distribution, tree shape, structure and other characteristics of wood. In contrast to a micro­ scopic examination, a macroscopic one is always more difficult and more uncertain. Never­ theless, it is useful in the field and does not require a lot of time or money. Users will find this bookhelpful in three ways:

- by being able to identifyan unknown species, to gain more information on the tree and its wood, - by being able to test and to confirm the identity of a speciesthought to be known and - by ascertaining whether an unknown wood is one of the main Guyanese species.

Questions of this nature come from biologists, teachers, researchers, carpenters and crafts­ men as well as from customs offices. The accompanying software enables a computer-aided description and identification, although many questions can be answered by consulting the book alone. The pack also includes a transparent scale grid for the determination of quanti­ tative structural features. Apart fromthese things, the user will need at least one very sharp knife and a hand-held lens. The features and the work to becarried out are described step by step. One important feature of the book is that the user can supplement it with additional wood species. The authors wish the user success and would welcome any criticism or sug­ gestions for improvement.

10 2 EXPLANATORY NOTES

2.1 Lens Key: Aims and Methods

What possibilities does this book offer? Tue- identification key which has been constructed for this field guide is based on a computer programme. It is complemented by a synoptical key if a computer is not available. The identification system is adaptable and allows specifications of the given descriptions, as well as additions of other species at any time. Because it depends not only on the sample but also on the user's knowledge and preferences, the sequence of features for description and identification is flexible (features can even be omitted!). Furthermore, the system works with different tolerances for errors which allow the user to take into account uncertainties of the descriptions. Apartfrom the identifying function, the system delivers information on the entered species, which can be viewed as a list on the screen or printed.

2.1.1 Tools A razor blade or sharp knife, a glass of water, the transparent scale grid with reference markings for measuring and evaluating different tissue types, a hand lens with a maximum magnification of 12 times, a pencil, the check-list with macroscopic features for field-work (the supplied form in the appendix is recommended to be used in copies), either a computer with the software "UniWoods2. 0" (see chapter 4.2), or the synoptic tables by species (see appendix). A printer and additional, specialized literature are of advantage but not abso­ lutely essential.

2.1.2 Preparing the sample The raw wood sample is cut or split in such a way that it can be easily examined later with the hand lens. Most features can be examined during field work in a clean cross section. If possible, we recommend the preparation of a cube of about 2 cm edge. Cross, radial and tangential surfaces should be vertical to one another and the radial and transverse surfaces should be aligned to the rays. The sample should not consist of juvenile wood and, whenever possible, should be taken from the heartwood (necessary in determining the colour of the heartwood). If the species investigated is a light wood, the cross section of the cube can be cut with a very sharp knife so that the structure is clearly visible. With hard types of wood, we recommend that the cube is first soaked and then boiled in a solution of 1 part water to 1 part glycerine. The boiling lasts it depends from several hours to 5-6 days in the maximum. This procedure facilitatesa clean cut across the grain.

2.1.3 Features The necessary features for description and determination are divided into two groups: - Group1: Features that have a code and are numbered from1- 95 . - Group 2: Features that have no code and therefore no number, but that nevertheless supply additional information important for the determination of the species.

Group Information on Features

Group 1 Vessels Visibility, arrangement, inclusions, diameter, density, proportion of solitary vessels Axial parenchyma Visibility, arrangement, parenchyma bands (absolute width, mutual distance, relative width) Ground fibre tissue Proportion of area Rays Visibility, relative width, absolute width, frequency, height Anatomical Growth rings, storied structures particularities Physical properties Density, heartwood colour, lustre, odour Group2 Additional features Canals, included phloem, oil or mucilage cells, other features

11 Programme structure Information as to the goal, degree of difficulty, tools, surface to be examined, method of evaluation and classificationis listed under each feature of chapter 4.1.

Degreeof difficulty I Features with one rectangle are generally easy to determine and can usually be classi­ fied under measurable criteria. They are therefore burdened with relatively less uncer­ tainty. II Features with two rectangles are generally more difficult to determine and therefore more difficult to classify. They are burdened with relatively greater uncertainty.

Classification The classification codes use two differentkinds of boundaries of classification: quantitative and qualitative. They are therefore either boundaries of dimension or boundaries that meas­ ure anabstract quality. - Quantitative: >(greater than),< (smaller than),<= (smaller or equal to). For example: <= 0.1 mm (smaller than 0.1 mm or equal to 0.1 mm) >0.1 - 0.2 mm (greater than 0.1 mm but not more than 0.2 mm). - Qualitative: For example: "distinct" or "indistinct".

Only one classification of a feature can be chosen, unless stated otherwise under "Method".

Illustrations An effort was made to limit the use of scientific terms. For those not familiar with the terms used, typical pictures are used to visualize their meaning in chapter 4.1. Such visual com­ parisons are more efficient than long, written definitions and replace the explanations of a glossary. The depicted features are often marked with arrows and their size is occasionally compared with black bars and rectangles (Figs. 14-17, 42-43,46, 54-56, 61-64) such as used with the transparent scale grid.

Specific information is given in the chapters 4. 1 and 4.2.

A) Synonyms The synonyms areimplemented from the Tropenbos Foundationand Polak (1992).

B) Vernacular name(s) The vernacular names are listed in alphabetical order, with an abbreviation forthe language to which a given name belongs in parentheses. These are all Amerindian languages, except for the Creole language. The following abbreviations are used:

Ak =Akawaio An=Arecuna Ar =Arawak C =Carib Cr =Creole M =Macushi P =Patamona W =Wapisiana Wr=Warrau

The vernacular name most commonly used in Guyana is given on the right hand side of the top line of each page with a description of the species being referred to. Most vernacular names were taken fromMennega et aL (1988).

13 Knowledge of the vernacular names is of vital importance for communication with local experts in forest work. On the other hand, knowledge of scientific names is often indispen­ sable when consulting botanicalliterature, Polak (19 92).

C) Field characteristics and distribution The information was excerpted from AM. Polak, Major Timber Trees of Guyana, A Field Guide, 1992. Detailed information about the forest- and soil types is found in the same book. Concerning the informations about tree height: e.g. "-30 m" means that the average tree of the pertinent species is 30 m high. "-30 (-40) m" means that the average tree is 30 m high and that the upper limit of height is ea. 40 m.

D) Map The hatched drawings show the distribution of the pertinent species. They were executed and put at our disposal by Mr.H.R. Rypkema and Mr. AM. Polak, University of Utrecht. The scale is ea. 1: 45'000'000.

E) Figures The magnification scale is 10. The two photographs (40 x 60 mm each) show the cross section of different individuals of the pertinent species to emphasize the anatomical vari­ ability. Because of this fact and the limited number of samples available, there are - in a few cases - features given in the written description which cannot be seen on the photographs.

F) Written description The description is split up into physical properties and structural features on the one hand, and anatomical features on the other hand. Non occurring features of a pertinent species are not especially mentioned in the text (e. g. "no distinct odour" or "axial parenchyma/fibres not storied").

G) Numbers of features in the key The numbers go from1t o95 and each number stands for a feature. A shaded number signal­ izes the occurrence of that particular feature. The numbers are the same as those used in the computerized key.

2.3 Indices

In order to facilitate the search for information on a particular species, indices are provided for both the scientific and the vernacular names of the species included in this field guide. These indices also serve as a dictionary for those who want to know the scientific equivalent of a local name, or vice versa. The legend of figures identifies the actual samples used throughout this work, particularly for the pictures.

2.4 Appendices

A) Synoptic tables by species B) Check list with macroscopic features for field-work C) Transparent scale grid D) Floppy disk The disk contains three files: ident2.exe (to identify an unknown sample), entry2. exe (to change or add data), and uniwoods.dat(comprises all the data; this file cannot be executed!). The software is explained in chapter 4.2.

4 FEATURES AND TREATMENT OF DATA

4.1 Explanations and Illustrations of Features

Vessels

1.1 Visibility - Goal: to judge the differentiation of vessels from the surrounding tissue with the naked eye - �gree of difficulty: difficult - Tools: none - Surfaceto be examined: crosssection

- Method: Examine the sample closely. Bright daylight or an adequate source of artificial light is indispensable. Glasses or contact lenses should be worn, if appropriate. The sample can be moved slightly backwards and forwards. The contours of the vessels beingexamined and their outline must stand out clearly in order to be classified as "distinct".

- Classifications: 1 distinct to naked eye 2 indistinct to naked eye

1.2 Arrangement and pattern (part. ref. "IAWA 1989) - Goal: to judge the arrangement and pattern of the vessels - Degree of difficulty: easy - Tools: hand lens, illustrations - Surface to be examined: cross section

- Method: Compare the arrangement of the vessels with the illustrations shownbelow. The dominant type is classified. More than one classification is possible.

- Classifications: 3 exclusively solitary (Figure 1) 4 solitary and radial multiples (Fig. 2) or clusters (Fig. 8/9) 5 exclusively radial multiples (Fig. 3) or clusters (Fig. 8/9) 6 radial multiples with individual vessels of the same diameter (Fig. 4) 7 radial multiples with individual vessels of different diameter (Fig. 5) 8 radial multiples of 2-4 vessels (Fig. 6) 9 radial multiples of >4 vessels (Fig. 7) 10 clusters of 2-4 vessels (Fig. 8) 11 clusters of >4 vessels (Fig. 9) 12 tangential pattern (Fig. 10) 13 diagonal pattern (Fig. 11)

19 20 1.3 Inclusions - Goal: to judge the contents of the vessels - Degree of difficulty: difficult - Tools: hand lens, illustrations - Surface to be examined: cross section, tangential section, radial section

- Method: Compare the content of the vessels with the illustrations shown below. Explanations: - Tyloses: light, often transparent tissue, with an appearance not unlike a cracked window-pane. Only found in heartwood and innon-conducting sapwood. - Inclusions: can be either light or dark. (Warning: in the cross­ and tangential sections, inclusions and tyloses look very similar and are easy to confuse). More than one classification is possible.

- Classifications: 14 no vessel content 15 tyloses present (Fig. 12) 16 organic inclusions present (Fig. 13)

1.4 Diameter - Goal: to determine the dimension of the largest vessels in mm - Degree of difficulty: easy - Tools: transparent scale grid, hand lens, illustrations - Surface to be examined: cross section

21 - Measuring method: Measure the tangential diameter by holding the transparent scale grid parallel to the rays. The five largest vessels (solitary vessels or individual vessels in clusters and multiples) are measured. The most frequently occurring diameter-class de­ termines the classification.

- Classifications: 17 <= 0. 1 mm; small (Fig. 14) 18 >O.l-0.2mm; medium (Fig. 15) 19 >0.2-0.3 mm; large (Fig. 16) 20 > 0.3 mm; very large (Fig. 17)

1.5 Vessels and vessel groups density (part. ref Lindeman and Mennega 1963; Laming and Jutte 1977) - Goal: to ascertainthe average numberof vessels, radial multiples or clusters per mm2 - Degree of difficulty: easy - Tools: transparent scale grid, hand lens, illustrations - Surface to be examined: cross section

- Measuring method: Count the number of vessels on an area of either 3, 5 or 10 mm2• The area chosen should have at least 20 vessels. The counting of the vessels within the chosen area is carried out at five dif­ ferent points. Vessels which are partially within the left-hand or the top boundaries are counted, those partially within the right-hand or bottomboundary are ignored.In order to facilitate the counting radial multiples or clusters count as one vessel. The average of five counts is converted (reduced) to correspond to an area of 1 mm2. Fractions should be rounded up to the next whole number and then classified.

22 Note: In order to expedite the identification process, it is advis­ able to count the multiples at the same time (see 1.6 - Propor­ tion of solitary vessels) and to calculate the percentage from the data obtained in 1.5 and 1.6.

- Classifications: 21 0- 2/mm2; extremely sparse (Fig. 18) 22 3- 51mm2; sparse (Fig. 19) 23 6-lO/mm2; somewhat sparse (Fig. 20) 24 11-20/mm2; fairly numerous (Fig. 21) 25 21-40/mm2; numerous (Fig. 22) 26 > 40/mm2; extremely numerous (Fig. 23)

1.6 Proportion of solitary vessels - Goal: to determinethe ratio betweenisolated vesselsand the total numberof vessels in % - Degree of difficulty: easy - Tools: transparentscale grid, hand lens, illustrations - Surface to be examined: cross section

23 - Measuring method: The number of vessels on an area of either 3, 5 or 10 mm2 is coWlted. The area chosen should have at least 20 vessels. The coWlting of the vessels within the chosen area is carried out at five differentpoints. Vessels which are partially within the left­ hand or the top boWldaries are coWlted, those partially within the right-hand or bottom boWldaries are ignored. The ratio of solitary vessels to the total number of vessels is calculated (%). The average of five coWltings is calculated and classified as follows:

- Classifications: 27 0- 33 % solitary vessels; few (Fig. 24) 28 > 33- 66 % solitary vessels; medium (Fig. 25) 29 > 66-100 % solitary vessels; numerous (Fig. 26)

5 Anatomical particularities

5.1 Growth rings (Anonymous 1960) - Goal: to recognise concentric layering of types of growth tissue (particularly of ves- sels, but also of fibre tissue) - Degree of difficulty: difficult - Tools: hand lens, illustrations - Surface to be examined: cross section

- Method: Compare the structure of the sample with those shown in the illustrations.

32 - Classifications: 75 growth ring boundaries indistinct or absent (Fig. 65) 76 growth ring boundaries distinct (Fig. 66)

5.2 Storied structures (IAWA1989) - Goal: to recognise a repetitive vertical layering of rays, the parenchyma or the fibres - Degree of difficulty: difficult - Tools: handlens, illustrations - Surface to be examined: tangential section

6 Physical properties

6.1 Density (Lignum 1963) - Goal: to assess the approximate density of the wood in g/cm3 - Degree of difficulty: easy - Tools: a glass of water, illustrations - Surface to be examined: whole sample

- Method: Put the sample, which must be air-dried, into the water. The position of the sample after 5-10 seconds is compared to the illustrations.

33 - Classifications: 80 low (Fig. 69) 81 medium (Fig. 70) 82 high (Fig. 71)

Note: The density values denoted with "low", "medium", and "high" vary widely in the pertinent literature. With reference to the method developed from Hoadley's (1990) idea, three classifications emerge. Neither the effective average density of the wood nor the classification boundaries are of direct relevance to the determination. How­ ever, the definition of the average density makes the results of the examination com­ parable to the literature data. For this reason, the density of 30 samples was deter­ mined and placed in order of magnitude in the 3 classifications "low", "medium" or "high" (depending on the position of the sample in the water). The classification boundaries are as follows:

low: >= 0.60 g/cm3 medium: > 0.6-1.04 g/cm3 high: > 1.04 g/cm3

�------___.,. not satisfactory satisfactory

study manual and definition of features used in the computer programme and start again with the input of data

46 The corresponding printouts are ob tained with the commands "show the ke ywords on print: yes" and "print all trees selected". The unknown wood sample is then compared to the listed pro posals (control). The same can be do ne by reading the information from the screen, but it is less easy to survey.

Special features - if occurring - appear at the end of each list of features. They are a conven­ ient resource forprecise identification.

The tree species proposal from the computer can also be visually compared with the un­ kn own wood sample with the aid of the macropho tographs which areincluded in chapter 5 .1.

The same can be do ne with a collection of woodsamples which have been reliably identi­ fied, labelled and stored in a du st-free environment.

As only a limited selection of features is stored in the computer, addi tional specialized lit­ erature can be of help.

An adequate combination of computer-solution and further resources de liver a satisfactory identi fication (=end solution) for all practical purposes. Where this is unsuccessful, a micro­ scopic examination of the woodbecomes necessary- ideally with the help of an expert with special kn owledge of woodanatomy.
