Hazel Bird Nature Reserve lies in the heart of Northumberland County’s  historical tallgrass landscape. The Reserve protects 118 hectares (292 acres) of oak woodland, Black Oak savanna, sand barren, and tallgrass prairie habitat and with it, the home of many species at risk.  


The Ontario Biodiversity Council has published a recent update to the State of Ontario’s Biodiversity: Extent, Quality and Protection of Ontario’s Rare Ecosystems. Southern Ontario’s tallgrass prairies and savannahs, although generally small in size, contain some of the rarest assemblages of plant and wildlife species in the province and most certainly, the country. As such, prairie and savannah ecosystems were chosen as “biodiversity indicators,” which are tracked through monitoring programs and other sources to inform the progress towards achieving Ontario’s 15 Biodiversity Targets and the status and trends in three biodiversity theme areas: 1). pressures on biodiversity; 2.) state of ecosystem, species and genetic diversity; and, 3). conservation and sustainable use.

To read the latest status update on the state of rare ecosystems in 2021, please see: Extent-and-quality-of-rare-ecosystems-2021-1

This and other information on indicators can be found here: Index of Biodiversity Indicators
