Past and Present Aspects of Czech Phytogeography and Climatology MILOS SEBOR A. INTRODUCTORY Phytogeography and climatology, two branches of physical geography, are related to every field of nature study, be it botany, pedology, geo- morphology, hydrography, or conservation of resources. The concept of the biotic triangle - an association of weather elements, soils, and vegetation - is a well-established platform for regional-physical inquiries. By the addition of topography we create a general framework for any geographic approach. Plant geography and climatology may be regarded, then, as fields which represent a greater part of nature study. This is true despite the specialization noticeable today in all divisions of human knowledge. Accepting the formula pars pro toto, a glance at plant geopraphy and climatology should suffice to cast some light, not only on the two selected disciplines, but on the whole body of natural sciences of a nation.1 The second objective of the present article is specific. What are the practical achievements of Czech 2 geographers in these two dynamic 1 For the general position of phytogeography and climatology among the earth sciences, cf. E. W. H. Briault and J. H.

Physical geography in Slovakia, according to Kreji! and others [quoted below] is still less developed 1668 Milos Sebor areas of earth's science? To what extent do Eastern and Western in- fluences meet in Czech geography? What are the changes? These are the main questions this investigator has in mind in attempting to intro- duce the reader to a field generally classified as less accessible to Western students because of language difficulties. B. OBJECTIVES, METHOD, AND AIMS The multiplicity of variables present in the natural and cultural environ- ment creates a variety of situations, problems, and solutions. Geography, a study of the earth's surface, is directly involved in this complexity and is necessarily a controversial subject, changing from period to period and from nation to nation. A fair prerequisite of any geographic study, therefore, is to specify the concept of geography as a logical system, based upon three variables - objectives, method, and aims. 1. Geofactors An areal investigation may first deal with phenomena qualifying as "geofactors", that is, agencies characteristic of the nature of the earth's surface. Viewed separately in their distributions, geofactors such as wind systems or types of plant cover make up the objectives of sys- tematic geography. If the combination of geofactors of a given area is studied, the inquiry becomes regional geography. The concept of geo- factors dominates postwar Czech geography.3 It may be, however, that geofactors do not qualify as objectives in the sense defined above. The earth's science, then, becomes a source of information on one element, or several elements, viewed separately, as a "related science", like botany, zoology, and mineralogy. than in Bohemia and Moravia, despite its rise. Slovak geographic centers are at this time (1) the Geographic Institute of Slovak Academy of Science; (2) the Chair of Physical Geography at the School of Nature Science of the Bratislava University; (3) the Teachers College at Presov; and (4) the Slovak Geographical Society, a branch of the Czechoslovak Geographical Society.

Method Next to objectives, the method [process, approach] is a criterion relevant to the classification of the earth science. It involves various stages of scientific inquiry. No matter whether the work is geographic or non-geographic, system- atic or regional, the method may be descriptive, or explanatory, or ap- plied. Description - explanation - application; ideally, these would be the three classic phases of the earth study. In geography, the descriptive stage includes the discovery of regions, collecting of facts, observation, and recording. Description does not necessarily mean an elementary approach. The great discoveries, a classically descriptive stage, were among the most remarkable achieve- ments of history. Today, of course, a mere description of the earth's surface would have no purpose in itself; it would be, rather, the basis of a more advanced study as a kind of "sub-geography". A higher level of geographic inquiry is formulating hypotheses, de- duction of further facts, testing the hypotheses, and eliminating the in- valid ones; the last step is to present theories based upon sufficient proofs. The aim of this second stage, which is basically analytic, is to interpret the geofactors previously discovered and recorded. The last stage is applied geography, that is, the proper and practical use of those elements described and explained, and of principles already produced. One function of this stage, which is basically synthetic, is the long-range forecasting of consequences, or a look into the possible distant future of the region. Another role of applied geography in this phase is its contribution to statecraft in the widest sense, and support of the ceaseless human effort to control man's terrestrial environment.4 Evaluation of the existing scene has increasingly become a guide to the development of the legislative process and to regional and city planning, general administration, and law enforcement. These are the main ideas relevant to a critical evaluation of the two selected branches of Czech geography. They pass through the well- defined historical phases, identified above as descriptive, or initial; the explanatory, or interpretative phase; and applied, or practical, phase. 4 S. W. Wooldridge and W. Gordon East, op. cit., p. 172. The emphasis on practical aspects of geography has been general in the last two decades. Cf., e. g., Status and Trends of Geography in the United States, 1957-60 (Washington, As- sociation of American Geographers, 1961), p. 27 ff; Pierre Dagenais, "M. Michel Phlipponneau" (honoring a French geographer, a representative of the école géographique ultra-moderne), Revue canadienne de géographie, Vol. XIII (January-June, 1959), p. 83. 1670 Milos Sebor C. DESCRIPTIVE PHASE As late as the second half of the nineteenth century, there was no in- dependent branch of geography concerned with the distribution of floristic and vegetational features. There was no climatology in the sense of a systematic analysis of weather elements studied over longer periods of time in their averages and extremes. Both plants and weather were observed and recorded within the regional framework. Czech geo- graphic writings reported on travels to various parts of the world, with attention to natural plant cover, such as types and density of forests, grassland, marshy land, and deserts. Examples include the first religion- inspired reports of trips to the Holy Land, and, later, the voluminous works of explorers, like Emil Holub's Sedm let v Jizru Africe [Seven Years in South Africa] of the 1890's. However, occasional attempts to explain geographic relationships - association of climate and vegeta- tion, for example - are not uncommon. The descriptive method was predominant in the first articles of geographic content, published in the Czech journal, Krok, founded by Josef Jungmann and edited by Jan Svatopluk Presl in 1821-36 as the forerunner of modern Czech learned journals.5 Distributions of the representative plant formations were shown on maps in the earliest period of cartography, going back to the 16th century. The most popular method was to use pictorial symbols for woodland and river bottoms, current until the nineteenth century, when Austria began detailed topographic surveys under the auspices of its army, and considerably improved all cartographic methods. D. EXPLANATORY PHASE During the second half of the past century, advanced geography became explanatory, or interpretative, dealing with causal relationships and, oc- casionally, with interconnections of the plant world and other physical elements, like climate, soils, and topography. The founder of advanced phytogeography was Jan K.
