Besides the great works by the AWC, Bush Heritage Australia is another highly worthy organisation (that I also support). Some of their achievements are listed below.
80.9 million: hectares of protected land we’re contributing to.
43.1 million tonnes: of carbon stock we’re protecting on our 37 reserves.
6359 native species: protected on our reserves and partners’ land.
243 threatened species: protected on our reserves and partners’ lands.
69 science projects collaborating with universities and research organisations to solve complex environmental problems.
25 Aboriginal partnerships: 11 partnerships on their land and 14 partnerships on our reserves to deliver positive conservation and socio-economic outcomes.
