Invasive Species

An invasive species is an introduced organism that negatively alters its new environment.  Although their spread can have some beneficial aspects (increased food source for birds and pollen and nectar for insect species), invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental and/or economic damage.

There are many invasive species that have made their way to areas in and around Otter Lake, the most notable being Zebra Mussels.  Unfortunately in many cases little or nothing can be done once an invasive species has been introduced.  That is why it is so important that everyone be diligent to ensure invasive specials are not accidentally or intentionally established in Otter Lake.

Since 2015 OLLA has concentrated efforts in eradicating, or at least limiting, European Frogbit though the help of volunteers and Rideau Valley Conservartion Authority (RVCA) by manually removing this invasive aquatic plant from Otter Lake.  The Federation of Cottagers’ Association (FOCA) also provided some funding.

In 2020/21 a major initiative in Ontario was launched to address Invasive Phragmites, an invasive plant which primarily inhabits wetlands but can be seen in drier areas.  Through funding received from FOCA, OLLA provided information to Otter Lake residents through mailings and signage.

OLLA maintains an information board at the boat launch and has published articles in our Newsletters on invasive species.  You are invited to also refer to the following documents.
