TL;DR: In this article, the authors evaluated the use of micro-catchments in the establishment of Leucaena retusa and Atriplex canescens and their role in the initiation of autogenic landscape restoration processes on a shallow semiarid site.
Abstract: Our objectives were to evaluate the use of microcatchments in the establishment of Leucaena retusa (little-leaf leadtree) and Atriplex canescens (four-wing saltbush) and their role in the initiation of autogenic landscape restoration processes on a shallow semiarid site. Three six-month-old seedlings of either Leucaena retusa or Atriplex canescens were planted in 1.5-m 2 microcatchments. An equal number of seedlings was planted in control plots (unmodified soil surface). The water collection effects on shrub survival, standing biomass, and the natural immigration of herbaceous vegetation were determined over 42 months. Planting in microcatchment basins doubled Leucaena seedling survival and resulted in a five-fold increase in standing biomass, compared to the control, during the first growing season. There was a significant increase in soil organic matter in the microcatchment basins within 32 months. At the same time, microcatchments planted with Atriplex canescens seedlings had a ten-fold increase in seedling standing biomass compared to the control. Forty-two months after transplanting, the herbaceous standing crop was significantly greater near Atriplex canescens or in microcatchment basins than in plots with unmodified surface soil. Basins containing Atriplex produced signficantly more herbaceous vegetation than basins containing Leucaena, and empty basins produced the least herbaceous vegetation of three basin treatments. These data suggest that landscape-scale procedures that concentrate scarce resources (water, organic matter, nutrients, and propagules), establish keystone species, and ameliorate microenvironmental conditions can initiate autogenic restoration of degraded semiarid ecosystems

TL;DR: Five of the seven North American native warm-season perennial legumes have promise for use in ruminant diets for the purpose of CH4 emission mitigation, strongly suggesting that CT MW does not explain the biological activity of in vitro CH4 production by the forage legumes surveyed.

TL;DR: There was a weak correlation between CT MW and percent LMI, suggesting that molecular weight of CT is a weak contributing factor to CT biological activity as it relates to LMI of L3 stage HC.

TL;DR: The results suggest that littleleaf lead-tree, awnless bush sunflower, and Illinois bundleflower would supply adequate supplemental forage from summer to fall; subterranean clovers, alfalfa, and sainfoin would provide foraging from winter through spring.
Abstract: Improving wildlife habitat through the introduction of nutritious forage species is a management tool that may be used to increase target populations such as deer. By increasing deer numbers the potential of leasing hunting rights on private land is improved. Our objectives were to evaluate and compare establishment and production of 2 browse species and to determine the production and nutritional quality among 6 forb species in range-land conditions. Browse species were littleleaf lead-tree (Leucaena retusa Gray) and four-wing saltbush (Atriplex canescens (Pursh) Nutt.). Forb species were 'Cody' alfalfa (Medicago sativa L.), 'Renumex' sainfoin (Onobrychis viciifolia Scop.), 'Howard' subterranean clover (Trifolium subterraneum L.), 'Nungarin' subterranean (T. subterraneum L.), 'Eldorado' Englemann daisy (Engelmannia pinnatifida Nutt.), 'Sabine' Illinois bundleflower (Desmanthus illinoensis (Michx.) MacM.), and 'Plateau' awnless bush sunflower (Simsia calva (Engelm. & Gray) Gray). Establishment for littleleaf lead-tree was 21%. Successful four-wing saltbush plants produced a greater volume (m3) of plant material than littleleaf lead-tree. Littleleaf lead-tree leaf material contained crude protein (CP) values from 11.6 to 16.9%. Of the cool-season forbs, alfalfa, and sainfoin produced the most above-ground phytomass at 23.6 and 22.6 g/m of planted row, respectively. The subclovers produced intermediate amounts of phytomass while Engelmann daisy produced negligible amounts at phytomass of 4.2 g/m of planted row. Warm-season forages, awnless bush sunflower, and Illinois bundleflower produced an average of 115.1 and 120.2 g/m of planted row, respectively. Seasonal CP means were greatest for alfalfa (16.5%) and awnless bush sunflower (16.1%). Our results suggest that littleleaf lead-tree, awnless bush sunflower, and Illinois bundleflower would supply adequate supplemental forage from summer to fall; subterranean clovers, alfalfa, and sainfoin would provide forage from winter through spring. Four-wing saltbush could provide forage year-round.

TL;DR: Expansion of leucaena into temperate regions of the world will require additional tolerance to freezing stress, and two species with more cold tolerance than L. leucocephala and Leucaena pulverulenta are identified.
