The Sydenham Field Naturalists initiative in establishing a one acre tallgrass prairie along hwy. 40 sparked the beginning of the Wallaceburg-Sarnia Prairie Passage by the Rural Lambton Stewardship Network. This one acre project was started in 1998 with the planting of 10000 grass and forb plugs on a low berm on the west side of Hwy. 40 just north of Whitebread Line. In 1999 another 2000 plugs were planted. In total approximately 20 species were introduced into this created prairie and $6500 was invested by the SFN.
The project started under difficult weather conditions and with extremely unfavorable heavy clay subsoil. To add to these problems, numerous aggressive non-native species such as Canada thistle and sweet white clover had to be eliminated. Over the next 10 years, with many, many hours of hot work by a few members, most of the weeds have disappeared although it will probably have to continue for the foreseeable future.
The Hwy. 40 prairie is now a success story and a real sense of pride for the SFN. Most of the original species still remain although a few have begun to dominate such as gray-headed cone flower, stiff goldenrod, tall sunflower, hairy beard tongue and big blue stem. Interestingly, some of the species are seeding themselves and expanding well beyond the original boundaries of the prairie.
