Development of a non-destructive method to assess vegetation structure and structural diversity of tussock grasslands at a landscape scale

摘要: Measurements of vegetation structure (the three dimensional placement the biomass) and structural diversity number layers present abundance within them) are required for numerous ecological questions. Several methods exist, but few time & resource efficient, appropriate measuring grasslands at a landscape scale non-destructive to vegetation. Furthermore, lack studies evaluating such makes it difficult ecologists choose which is most appropriate. A novel, method both (using aerial photographs) being developed. The results attained will be compared with those yielded by two established employed estimating (“Height Frequency Method” (Dickinson 1992) “MacArthur (MacArthur 1961)) as well presence/absence data considered baseline; representing vegetative community no information about or diversity. limitations existing presented followed an overview developments date “novel aerial-photo method”. request advice suggestions made.
