Remote monitoring of abandoned grasses invaded by Pteridium aquilinum (L.) kuhn and Cytisus scoparius (L.) link.
In Romania, grasslands can be seen as a major component of rural development, contributing significantly, through goods and services in the socio-economic sector and environmental protection. However, the grasslands are marked by obvious signs of abandonment. In this context, the aim of the paper is to test vegetation indices for monitoring abandoned grassland areas in Banat, invaded by the species Pteridium aquilinum (L.) Kuhn and Cytisus scoparius. Remote sensing indices were applied in the GIS environment, on high spatial resolution aerial images, among them, Excess Green Index, having the most relevant results. In the case of the analyzed grassland, the values of Excess Green Index show the advanced stage of degradation, signaled especially by the presence on large areas of invasive species Cytisus scoparius and Pteridium aquilinum (L.) Kuhn, but also of different shrub formations. More than 50% of the grassland area may not be used for agricultural purposes.
