The effects of thinning Emory oak ( Quercus emoryi) coppice on transpiration have been estimated by the heat-pulse velocity (HPV) method. Rootstocks of trees harvested for fuelwood were thinned to one, two, or three dominant stump-sprouts or left as unthinned controls. Differences in transpiration rates of the thinned coppice were found for each treatment and the control. Earlier research has also shown that thinning of Emory oak stump-sprouts influences the growth and volume of the residual coppice and its value for wildlife habitats. Therefore, a decision matrix is presented to help in the management of thinned Emory oak coppice for optimal combinations of water, wood, and wildlife benefits.

Let the Water Do the Work is an important contribution to riparian restoration. By "thinking like a creek," one can harness the regenerative power of floods to reshape stream banks and rebuild floodplains along gullied stream channels. Induced Meandering is an artful blend of the natural sciences - geomorphology, hydrology and ecology - which govern channel forming processes. Induced Meandering directly challenges the dominant paradigm of river and creek stabilization by promoting the intentional erosion of selected banks while fostering deposition of eroded materials on an evolving floodplain. The river self-heals as the growth of native riparian vegetation accelerates the meandering proces...
Rainwater Harvesting for Drylands and Beyond, Volume 2, 2nd Edition is a how-to guide enabling you to “plant the rain” by creating water-harvesting “earthworks” or “rain gardens.” Earthworks are simple, inexpensive strategies and landforms that passively harvest multiple sources of free on-site water including rainfall, stormwater runoff, air conditioning condensate, and greywater within “living tanks” of soil and vegetation. The plants then pump the water back out in the form of beauty, food, shelter, wildlife habitat, timber and forage, while controlling erosion, reducing down-stream flooding, dropping utility costs, increasing soil fertility, enhancing the soil carbon spon...
Gambel oak (Quercus gambelii) is a key deciduous species in southwestern ponderosa pine (Pinus ponderosa) forests and is important for wildlife habitat, soil processes, and human values. This report (1) summarizes Gambel oak's biological characteristics and importance in ponderosa pine forests, (2) synthesizes literature on changes in tree densities and fire frequencies since Euro-American settlement in pine-oak forests, (3) suggests management prescriptions for accomplishing various oak management objectives (for example, increasing diameter growth or acorn production), and (4) provides an appendix containing 203 Gambel oak literature citations organized by subject. Nine studies that recons...
