These data and analyses support the research article "Wild ungulate herbivory suppresses deciduous woody plant establishment following salmonid stream restoration" Averett et al. (2017) [1]. The data and analyses presented here include: (1) planting density, survival and growth (two years post restoration) of riparian plantings along an ~11 km stream reach in northeastern Oregon as a function o...
Woodland birds are a species assemblage of conservation concern, and their persistence in fragmented agricultural landscapes is dependent on both the preservation existing woodland remnants implementation restoration plantings. However, little known about habitat-use landscapes. We present detailed, population-oriented study temperate eucalypt plantings remnant patches South-west Slopes bioregi...
Abstract American ginseng ( Panax quinquefolius L.) is an herbaceous perennial plant native to the forests of eastern North America with a long history use and harvest, significant international market. To supply demand, grown in USA Canada under artificial shade cloth. However, wild wild-appearing roots command prices up 100 times greater than cultivated field: $550–2200 (US$ dry kg) vs. $20–7...
Pocket gophers cause extensive damage to reforestation plantings in the western United States, and pose acute and chronic problems for forest managers. We examine the components of an integrated pest management strategy for reducing pocket gopher damage to conifers: the predictive factors for assessing the risk for damage, techniques for monitoring gopher populations and assessing efficacy of c...
To study the effects of species diversity different urban road green space on PM2.5 reduction, and to provide a theoretical basis for optimal design plantings. Different combinations plantings in Xianlin Avenue Nanjing were used as sample areas, 3–6 monitoring points set up each area. The setup at 10, 20, 30, 40, 50, 60 m from roadbed detecting concentrations areas. Moreover, living vegetation ...
