Prosopis

帮助我们通过利用地理参照图片地图牧豆树的入侵

Large parts of semi-arid areas in Eastern and Southern Africa are reportedly invaded by P. juliflora and the expansion is rapidly increasing especially in communal grazing areas and along the road and hydrological networks. Despite the extensive impact of P. juliflora on ecosystems and livelihoods, methods for assessing its distribution are scarcely developed. This app aims at supporting the mapping of Prosopis Juliflora on satellite imagery by providing ground information on invasion hotspots. When taking pictures of Prosopis plants in areas known to you, it is important to include pictures also about surrounding natural vegetation in order to distinguish it from other plants. It is also important to take several pictures in for one invasion area to understand the different shrub and tree shapes which are present, since this species presents itself in many forms from small shrubs to large trees.
