Riparian Buffer Restoration
Pennsylvania Stormwater Best Management Practices Manual Chapter 6 BMP 6.7.1: Riparian Buffer Restoration A riparian buffer is a permanent area of trees and shrubs located adjacent to streams, lakes, ponds, and wetlands. Riparian forests are the most beneficial type of buffer for they provide ecological and water quality benefits. Restoration of this ecologically sensitive habitat is a responsive action to past activities that may have eliminated any vegetation. Key Design Elements Potential Applications Residential: Yes Commercial: Yes Ultra Urban: Yes Industrial: Yes Retrofit: Yes Highway/Road: Limited · Reestablish buffer areas along perennial, intermittent, and ephemeral streams · Plant native, diverse tree and shrub vegetation Stormwater Functions · Buffer width is dependant on project preferred function (water quality, habitat creation, etc.) · Minimum recommended buffer width is 35’ from top of stream Volume Reduction: Medium bank, with 100’ preferred. Recharge: Medium · Create a short-term maintenance and long-term maintenance Peak Rate Control: Low/Med. plan Water Quality: Med./High · Mature forest as a vegetative target · Clear, well-marked boundary Water Quality Functions TSS: 65% TP: 50% NO3: 50% 363-0300-002 / December 30, 2006 Page 191 of 257 Pennsylvania Stormwater Best Management Practices Manual Chapter 6 Description The USDA Forest Service estimates that over one-third of the rivers and streams in Pennsylvania have had their riparian areas degraded or altered. This fact is sobering when one considers the important stormwater functions that riparian buffers provide. The non-structural BMP, Riparian Forest Buffer Protection, addresses the importance of protecting the three-zone system of existing riparian buffers.

Invasive Plants: Ecological Effects, Status, Management Challenges in Tanzania and the Way Forward

Ngondya*, Anna C. Treydte, Patrick A. Ndakidemi, Linus K. Munishi 1Department of Sustainable Agriculture, Biodiversity and Ecosystem Management, School of Life Sciences and Bio-Engineering. The Nelson Mandela African Institution of Science and Technology, Arusha, Tanzania Article published on March 31, 2017 Key words: Competition, Allelopathy, Weeds, IPM, Mowing Abstract Over decades invasive plants have been exerting negative pressure on native vascular plant’s and hence devastating the stability and productivity of the receiving ecosystem. These effects are usually irreversible if appropriate strategies cannot be taken immediately after invasion, resulting in high cost of managing them both in rangelands and farmlands. With time, these non-edible plant species will result in a decreased grazing or browsing area and can lead to local extinction of native plants and animals due to decreased food availability. Management of invasive weeds has been challenging over years as a result of increasingly failure of chemical control as a method due to evolution of resistant weeds, higher cost of using chemical herbicide and their effects on the environment. While traditional methods such as timely uprooting and cutting presents an alternative for sustainable invasive weeds management they have been associated with promotion of germination of undesired weeds due to soil disturbance. The fact that chemical and traditional methods for invasive weed management are increasing failing nature based invasive plants management approaches such as competitive facilitation of the native plants and the use of other plant species with allelopathic effects can be an alternative management approach. -

2.12 Stream temperature and buffers Buffers can help maintain cooler water temperatures in small streams if the vegetation provides adequate shade on the water surface. This can be beneficial for coldwater aquatic species and for water quality. Stream shade is comprised of topographic shade provided by nearby hills, bank shade, and vegetative shade. Streams with vegetation removed usually have undesirable summer temperature increases from 5 to 11oC. Aspect, channel morphology, and groundwater input may affect temperatures more than buffers. Key Design Considerations • Incorporate topography and bank shade in the design. • Trees and shrubs provide the most shade but unmowed or ungrazed grass buffers can provide shade on streams less than 8 feet in width. • Buffer shading effectiveness decreases as stream width increases. • Windthrow may be common in buffers retained after timber harvest and wider buffers may be necessary. • Buffers may need to be wider (150 to 1000 ft) to maintain other microclimatic factors (e.g., soil temperature, humidity). 2.12 Biodiversity 2.12 References Anbumozhi, V.; Radhakrishnan, J.; Yamaji, E. 2005.

Chemotaxonomic Significance of Hydroxylated
Biochemical Systematics and Ecology 26 (1998) 379Ð401 Chemotaxonomic significance of hydroxylated pipecolic acids in Central American Inga (Fabaceae: Mimosoideae: Ingeae) Timothy C. Morton* The Pennsylvania State University, Pesticide Research Lab, University Park, PA 16802, USA Received 30 May 1997; Accepted 22 July 1997 Abstract Hydroxylated pipecolic acid derivatives of 47 species of Inga were analyzed primarily from herbarium leaf samples supplemented by field collections. Inga species are noted for their morphological variability, which has resulted in considerable taxonomic confusion. Pipecolic acid chemistry appears to be a relatively stable character within species, and the large number of pipecolic acid derivatives translates to greater intraspecific diversity in chemical patterns (18 distinct hydroxypipecolic acid patterns) than previously found in related genera. This chemical diversity makes pipecolic acids particularly useful in solving taxonomic problems in this genus; problems such as identification of distinct species with convergent morphology and identifica- tion of mislabeled herbarium specimens. Chemistry provides data independent of morphology with which to assess recent changes in nomenclature (some of which are supported, others not) and may also be useful in the assessment of hybridization and in delimitation of proper species boundaries. At present our chemical knowledge is too fragmentary to allow strong statements regarding relationships above the species level, but there is a trend for taxa traditionally grouped on morphological criteria to share similar chemistries.

Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -
