Large herbivore biomass in protected areas

Large herbivores provide key ecosystem processes, but have experienced
massive historical losses and are under intense pressure, leaving current
ecosystems with dramatically simplified faunas relative to the long-term
evolutionary norm. Hampered by a shifting baseline, natural levels of
large-herbivore biomass are poorly understood and seldom targeted. Here,
we present a collation of large-herbivore biomass data from
published sources as well as personal communication. The data includes
continent, ecosystem name, latitude, longitude, large
herbivore biomass in kg/km2 and the source of the data.
It can be used together with net primary productivity
(e.g., using satellite-derived NPP retrieved from
http://files.ntsg.umt.edu/data/NTSG_Products/MOD17/GeoTIFF/MOD17A3/GeoTIFF_30arcsec/) to explore the scaling relationship between producer and consumer.
