Effectiveness of integrated shrub management and restoration techniques for rehabilitating shrub‐encroached rangelands of South Africa

open access: yesGrassland Research, EarlyView.
Herbaceous plant recovery following shrub clearing and reseeding in the rangelands of Peddie, Eastern Cape of South Africa. CTL, control; CO, cutting only; CR, cutting and reseeding; UPO, uprooting only; UPR, uprooting and reseeding. Abstract Background Shrub encroachment (SE) drives rangeland degradation, threatening biodiversity and forage ...

Airborne laser measurements of rangeland canopy cover and distribution

open access: yes, 1992
Studies were made at 2 rangeland areas in south Texas to measure canopy cover and distribution with an airborne laser profiler. In a comparison of laser and ground measurements of canopy cover on the same eighteen 30.5-m segments at the Yturria area ...

Satellite optical remote sensing of forest canopy cover in boreal and tropical biomes

open access: yes, 2018
Continuous field of tree cover, or canopy cover (CC) is an important information required in ecology and international forestry. In ecology, CC quantitatively depicts the spatial heterogeneity of tree cover, and is therefore useful for spatially-explicit

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

open access: yesGrassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.

Quantifying change in urban tree cover in the city of Lubbock, Texas, using LiDAR and NAIP imagery fusion

open access: yesScience of Remote Sensing
Urban tree cover provides important ecosystem services, such as the maintenance of biodiversity, the conservation of water, and human health. An accurate estimate of the canopy cover of urban trees is essential to quantify spatial variations, monitor ...

Evaluation of sunn hemp performance and nutritive value in Maine, USA

open access: yesGrassland Research, EarlyView.
Abstract Background Sunn hemp (Crotalaria juncea L. and Crotalaria ochroleuca G. Don) was evaluated as a warm‐season legume to mitigate the “summer slump” in Maine's forage production caused by heat and moisture deficit stress. Methods This study compared three cultivars: “Crescent Sunn,” “Loei,” and “Red Mini,” at 60 and 90 days after seeding over the

Genomic selection for nitrogen use efficiency in perennial ryegrass (Lolium perenne L.) under field conditions

open access: yesGrassland Research, EarlyView.
There is genetic variation in ryegrass for the ability to respond to nitrogen fertilizer, Breeding nitrogen use efficient cultivars can increase farm profitability and sustainability. Abstract Background Improving the nitrogen use efficiency (NUE) of pastures has the benefit of reducing costs of production and reducing nitrogen loss to the environment.
