Deer Haven is an incredible 19.4-hectare nature reserve with a diverse mix of habitats including mature forests, prairie and early successional woodland. This former farm has been actively restored by Heather and Peter Scott for more than 25 years. Deer Haven contains a tributary of the Thames River including critical habitat for species at risk fish and mussels. The variety of habitats and proximity to the Thames River make this a key site to protect for long term sustainability of biodiversity.

Ridgeview Wetlands is a 13-hectare nature reserve that is part of the 178.8 ha Five Points Woods Wetland Complex, a Provincially Significant Wetland and an important wildlife refuge. The site is along the Ingersoll moraine with steep wooded ridges and deep wetland troughs. Extensive woodlands on this nature reserve are important for area sensitive birds, several of which are Species at Risk. The nature reserve is home to at least three Species at Risk birds that depend on interior forest habitat and at least 35 priority species in Bird Conservation Region 13. The seep-fed wetlands on the property are especially important for amphibians and Species at Risk turtles. TTLT has an active turtle recovery program at the Five Points Woods Wetland Complex for Midland Painted Turtle and Snapping Turtle.
