over the past 2 years head researcher janine mcmanus and a group of students have recorded the number of plant species in selected study sites. in addition the group evaluates the earth budgetary index the index is determined by the amount of green seen on the ground by satellites and allows researchers to compare progress in different regions over time. and you can already start picking up changes in trains with the way the hood has been grazing especially over a longer recent period in parts of the farm and the green index shows up quite pronounced and we compared it to traditional farms where it isn't quite as pronounced and they seem to be quite a significant color it's just looking at the pixels alone you know taking the green out of pixelization but from that alone you can really start seeing a difference. there are many positive signs. areas that have been grazed by the herds are now seeing thicker plant growth. slowly while the animals are returning to the farm more than 500 antelope have been counted and even a leopard was recently sighted. a major success for dixon cool espe
