Shareholder Update: Biological Control Initiative for Purple Loosestrife
Good morning Shareholders,
I would like to provide a quick update on our ongoing efforts to protect the vital areas surrounding our canals, laterals, and ponds.
One of our initiatives is the release of biological control insects to help manage and contain Purple Loosestrife. Because this invasive species thrives in the semi-aquatic habitats of our waterways, applying chemical herbicides is often difficult or impossible in hard-to-reach areas. Instead, biological control has become our primary management strategy.
Our Partnership and Progress
We continue to work closely with Denise Helsley, the Noxious Control Superintendent for our area. This marks our second consecutive year releasing the Root-boring Weevil (Hylobius transversovittatus) into heavily populated Purple Loosestrife zones.
While the adult weevils feed on the plant's leaves, it is the larvae that do the heavy lifting. They burrow into and mine the taproot over a one- to two-year period, which stunts the plant’s ability to reproduce and ultimately kills it.
Why Control Purple Loosestrife?
Purple Loosestrife is a highly aggressive, non-native w**d that poses a serious threat to our infrastructure and local environment. Left unchecked, it:
Outcompetes crucial native vegetation.
Decimates valuable wetland habitats.
Disrupts local ecosystems and water flow.
How You Can Help
If you notice a Purple Loosestrife infestation on your own property, we encourage you to take action. You can contact your local county w**d control board or the ISDA’s Noxious W**d Program to:
Request a release of biocontrol insects.
Inquire about gathering established beetles from nearby public lands for relocation.
To find the specific contact information for your region, please visit the Idaho Invasive and Native Species Resources directory.
Thank you 😊
