TBFN Reserves

Pictured Lake Addition

Thunder Bay Field Naturalists are seeking your support to purchase a new nature reserve property, a 116-acre parcel abutting our existing Pictured Lake Nature Reserve near Oliver Lake. The original Pictured Lake Reserve, purchased in 2008, protects 105 acres of land surrounding a small lake. We already have an accepted offer to purchase this adjacent property with a closing date of May 27, 2021. 

This new nature reserve will add to the protection of the existing reserve. Oliver Creek, the outflow from the lake, flows through the length of the new property. The creek has many beaver ponds and dams, and interesting plants including Jack-in-the-pulpit, Bloodroot and Wild Ginger growing in the rich floodplain. Western Painted Turtle eggs were found by the stream. The property is covered with mature mixed forest which includes some large White and Red pine. At the south end of this parcel is a high rock outcrop with Jack Pine, Sugar Maple, Red Maple, Spikenard and Sumac. See map and photos to the right.

TBFN needs your donations to support this purchase. Although we have some funds set aside already, and will seek matching grants, we depend on the support and generosity of our own members to move forward with this purchase. 

Donations may be made using any major credit card or PayPal on this website. Click here to be taken to the donation form. Please indicate that your donation is for “Nature Reserves” if you choose this method. The Club can also accept donations of stocks and bonds. (This may have some tax advantages for larger donations – talk to Sue Bryan about this if you are interested. She can be reached by email at, phone: (807) 345-6446) or (807) 627-4556.) 

TBFN is a registered charity and will provide a tax receipt for all donations.

The Purpose of Our Nature Reserves

The main purpose of the Thunder Bay Field Naturalists Nature Reserves is to protect the natural habitats, birds, plants and animals that live in these special places. We do not maintain trails, parking lots, fences, gates or any other facilities at the nature reserves.The Reserves are there largely for protection, with recreational uses of secondary importance. We encourage you to visit and quietly enjoy the TBFN Reserves, while respecting the special natural features there. Motorized vehicles, including ATVs, snowmobiles, and dirt bikes, are not allowed. Hunting, overnight camping, and campfires are also prohibited. If you need detailed directions on how to find these locations please contact the Nature Reserves Chair. Visitors are welcome to join in on club field trips that go to many of the reserves. We invite you to come along.  


We are always looking for help with our Nature Reserves. You can “adopt” a reserve by acting as a stewardship volunteer. Activities include monitoring for inappropriate uses, reporting wildlife sightings, planting trees, and removing trash. For more information, please contact the Nature Reserves Chair.
