Native flora and fauna have evolved to attain an ecological balance and rhythm that is self-sustaining. Both plant and animal, including insect, populations not native to this area can move in and disrupt or displace native populations. This happens through gardening, climate change, destruction of natural habitat, and more.
Some examples include the recent LDD (formerly gypsy moth) caterpillar infestation, phragmites, a tall ornamental grass that forms a very dense mat and spreads rapidly, and Giant Hogweed that can cause severe burns.
Losing wild greenspace, forests, woodlots and wetlands and even farmland to built-up areas has a devastating effect on the number and variety of plants and animals we share this land with.
- Disruptions to these otherwise robust systems can mean pollinators out of sync with blossom time, the use of toxic chemicals to reduce pest populations, and reduced biodiversity.
