Restoration of highly eroded desert land was attempted in the southern Sonoran Desert that had lost its natural capacity for self-revegetation. In six field experiments, the fields were planted with three native leguminous trees: mesquite amargo Prosopis articulata, and yellow and blue palo verde Parkinsonia microphylla and Parkinsonia florida. Restoration included inoculation with two of plant...
HIGHLIGHTS • Vegetation structure and composition were measured in four major green space types • Remnants and golf courses supported highest native plant richness • Residential neighborhoods and urban parks supported highest exotic plant richness • Residential neighborhoods lacked key habitat structures including old trees • Green spaces can achieve complex vegetation with both native and exot...
Residential yards are a form of urban land use that cover considerable amount area in cities worldwide and provide important habitat for wildlife, especially when landscaped with native plants. Nevertheless, most native-plant landscaping wildlife research the northern temperate regions world has been conducted during spring summer breeding period, leaving gap our understanding importance reside...

Amentotaxus formosana Li is a native, tolerant, and under-wood species in Taiwan. This particular species is only distributed around the Chachayalaishan and Dawushan areas. Because of its rarity, and the endangered and native properties of the species, we explored the regeneration process of the species in the native environment. This paper, therefore, aims to outline the age distribution and g...
Dry forests are the most threatened biome across global tropics (Blackie et al., 2014; Miles 2006). Massive dry forest conversion into mostly treeless pastures and crop fields has decreased biodiversity, altered vegetation-climate feedbacks biogeochemical cycles (Harrison & Bruna, 1999; MEA, 2005) diminished positive contribution trees can have on farm productivity livestock well-being (Harvey ...
The genus Elaeagnus (Elaeagnaceae) has been introduced in Iran by one or two species, i. e. E. angustifolia and E. orientalis . The species are widely cultivated trees, but native in a few localities. They are extremely variable in shape of leaves and fruits. Fruits used to be eaten highly and as they have variable tastes, the preferred ones have been subject to selection in the course of time....
