York Simcoe Nature Club

Cultivating an appreciation of nature through learning and action

About us


York Simcoe Nature Club, formerly know as York-Simcoe Naturalists, was formed in 1999 by a small group of individuals who had a strong interest in the environment and who wanted to share this interest with other people. The Club has operated continuously since 1999 and has grown from its small beginnings to a membership of over 60 individuals. It is run by an elected executive who is responsible for the various aspects of the operation.

The Club provides a venue for York Region and Simcoe County residents who have a special interest in outdoor recreation and natural history to get together and share ideas, expertise, community projects and local natural history. The Club also serves as a unified voice to constructively influence municipal planning, environmental awareness and environmental protection, particularly locally. In view of the integrated nature of the environment, the Club is also concerned with developments and changes in the natural environment in other areas.

Members of the Club benefit through:

Although York Simcoe Nature Club is an independent club, it is a member of Ontario Nature's 150-plus Nature Network, Neighbourhood Network, Lake Simcoe Stewardship Group and Ontario Greenbelt Alliance. For more information on these organizations, go to Links.

Special projects

Every year the Club initiates a special project for which money is raised through donations.

These walks not only provide an opportunity to enjoy the outdoors, but also an opportunity to learn about nature as members share their specific skill, be it flowers, birds, trees, butterflies and more.

York Simcoe Nature Club is the steward of the Cawthra Mulock Nature Reserve. The Club has held this responsibility since 2007 under various agreements with Ontario Nature, the owner of the land.

The Reserve is located between Bathurst and Dufferin streets just north of Miller Sideroad in the Township of King. This 108 hectare property was donated by Mrs. Julyan Mulock and the Cawthra Mulock Foundation to Ontario Nature in 2003 to ensure that the property would be protected in perpetuity. Ontario Nature owns the Reserve in fee simple and the Ontario Heritage Trust holds a conservation easement of the land.

The terrain within the Reserve is flat to undulating except for steeper banks on the northern most watercourse which traverses the property. There is another watercourse toward the southeastern portion of the property. These watercourses, which flow perennially, are tributaries of the Holland River. There is a diversity of ecosites on the property. The dominant ecosites are mineral cultural meadow and Hemlock mixed forest with smaller areas of coniferous plantation, White Birch and Sugar Maple deciduous forest and open aquatic. There is a wetland in the south western portion of the property which is part of the Ansnorveldt wetland complex. A wide variety of plants, birds, animals and insects make this property home both seasonally and year round.

As stewards of the Reserve the York Simcoe Nature Club members have worked with Ontario Nature on many projects including the following:
