The War on Invasives


I started this blog last year and never got it finished. Then two weeks ago,  two summer techs and I went to a two day workshop on identifying and managing invasives.  The main thrust was learning when and with what to spray invasive plants. I learned a lot, even though I've been working on managing invasive plants for many years in different parts of the country. The class was in the town of Whitehall, Montana which was a cute little town with a beautiful mountain backdrop

Out classroom had about eighty students

I was excited to get a prize for answering a review question and even more excited to pass the two tests, even though I hadn't even looked at one of the study books.  I may now be able to take better selfies, with and extra forty-two inches of reach.

Why, you ask are invasives such a big deal?  Can't these aliens just live among the natives?  No, the local food chains require native plants for the native bugs for the native birds.  But the invasive plants replace native plants, sometimes forming huge monocultures that are like deserts to the native animals. They don't have insect pests that would help keep them in balance. Some of them are poisonous to birds or mammals, including livestock.

In Montana, invasive plants are assigned to one of four classes. Priority 1A weeds are not yet present in Montana, but people are watching for them to arrive.  Priority 1B weeds are only found in a few spots and are to be eradicated where they are found and people  educated to watch for them elsewhere.  Priority 2A weeds are common in parts of Montana and 2B weeds are abundant across Montana. It is the law that you may not allow any of these weeds to go to seed on your property.  Every  private or government entity has a weed management program in place and has spray crews. We have several entities in the valley that have spray crews. Several times during the summer, we will all come together to fight one particular weed at one location.


 Last year, one of our valley wide weed battles started at Red Rock Pass and came down into the refuge. Some of the crew sprayed but the people I was with pulled hoary alyssum by hand, filling a pickup truck full of black garbage bags.

I, of course, was easily distracted and stopped for butterfly pictures

This is my boss, Bill West, and Jessica Zapata, the leader of the Fish and Wildlife Strike Team.  She visits all the national wildlife refuges in Montana with several workers.  They spray from ATV where there are extensive infestations. We see her here a couple of times during the summer. 

I love these group efforts, because I know many of the people, having met them in previous years. At some of the meetups, we get a catered lunch and take time to visit.

Great food and company


Bill took us down a short trail to a wolverine trap.  The trap sends a radio signal when it is tripped- a top built of logs closes .  The trappers have to rush to the trap because the wolverine can chew through the logs pretty quickly.  Sometimes, they chew out but hang around to chew a bigger hole to get up the deer leg used for bait. 

This week, I  spent my first full day of this year working on weed control.  Two techs, Kyle, and Micky. and I went to an old homestead site and cut down Russian Pea, a shrub that makes edible peas, planted by the settlers.  Then we painted the cuts with an herbicide to prevent resprouting.  The kids also dug up two bags of houndstongue.

I'm late with this blog because I didn't get a day off this week.  We have had mostly rainy days, except for weed day.  It was too cold and wet to open the bluebird boxes on Monday, so I spent a long day on Tuesday on that.  I only worked 5 hours on Monday, so planned to work a few hours on Friday to catch up.  But on Thursday, Bill told me he had paid for me to go to the Wilderness First Aid and CPR class.  He thought he was reminding me. The class ran from Friday noon until 5:15 today (Sunday).  So I'm trying to get my Sunday blog out before Monday gets here. I totally enjoyed the class and learned that a lot of standard stuff has changed. We don't even use backboards any more and transport people with suspected spinal injuries on their sides.

We are supposed to have a valley wide spray day Tuesday. But we are supposed to have rain continue through Tuesday, so I expect that will be canceled.  I will probably take most of the day off tomorrow but will have to take a load of water to the horses by Tuesday. I also have to work around the wet, as there are a couple of places where the truck may get stuck if the ground is too soft.


Happy Father's Day to all you fathers.
