The Northern Monaro Reserves contain vegetation communities which are not being well-represented elsewhere in the conservation system. These provide habitat for 3 threatened plant and 6 threatened animal species, including the koala, spotted-tailed quoll and eastern bentwing-bat.
The reserves contain a number of Aboriginal sites and are part of the traditional area of the Ngarigo people. They also contain evidence of gold mining and associated activities that took place from the 1880s to the early 1900s, including mine shafts, diggings, dams, huts sites and dry stone wall embankments.
