Central & Eastern Montana Invasive Species Team

Central & Eastern Montana Invasive Species Team CEMIST leverages the work of all of these partners through education, outreach and advocacy. CEMIST also has an active Advisory Council.

The CEMIST mission is to leverage the invasive species prevention work of our state and local partners through Education, Outreach, Advocacy, and rural communities. Background:

The Central and Eastern Montana Invasive Species Team (CEMIST) is a voluntary group that strives to create collaborative partnerships with local, regional, state, and federal organizations to address invasive species is

sues. Although it has federal and state partners, the group has a regional focus on an underserved area. It is comprised of representatives from several Conservation Districts, Montana Fish, Wildlife and Parks (FWP), various watershed groups, and Montana Invasive Species Council (MISC) members. The purpose of CEMIST is to protect and preserve the economy and natural resources of Central and Eastern Montana from current and future invasive species threats. Priority invasive species include feral swine, aquatic invasive species (AIS), woody invasive trees (i.e. salt cedar, Russian olive, & common buckthorn), eastern heath snail and annual invasive grasses. CEMIST achieves its mission by increasing local awareness of all invasive species with its own information and by utilizing material from its partners. Specifically, CEMIST works with the Department of Natural Resource and Conservation (DNRC), Natural Resources Conservation Service (NRCS), Montana Association of Conservation Districts (MACD), and National Association of Conservation Districts (NACD), as well as several local MSU Extension offices. At a more local level, the group also partners with the Musselshell River Cooperative Weed Management group and is working towards getting more involvement from local weed districts. This integration of various organizations results in a unified message being delivered to the public, regardless of its source. Purpose

When the Japanese beetles vanish in late summer, the real problem is just moving underground. The females already laid eggs in your North Carolina lawn, and the grubs feeding on your grass roots right now are what brings the swarm back worse next summer. Treating the turf in fall breaks that cycle before winter sets it in stone.

🚨Emerald Ash Borer Detected in Central North Dakota

Emerald ash borer (EAB) has now been detected in Bismarck, North Dakota, putting communities across the state on alert.

This destructive insect has killed hundreds of millions of ash trees across the U.S.

North Dakota has more than 90 million ash trees, making EAB a serious threat to our forests, parks and communities.

HELP STOP THE SPREAD:
❌ Don’t move firewood.
🔥 Buy firewood locally or gather it where permitted.
🌳 Don’t transport ash logs, branches, nursery stock or wood chips from quarantined areas.
👀 Learn how to spot EAB and report suspected infestations.

EAB typically spreads naturally only a mile or two, but people can accidentally transport it hundreds of miles through firewood and other ash materials. Your actions can make a difference. Help protect North Dakota’s ash trees by leaving firewood where you got it. 🌳

Japanese Beetles in Montana:

Fall Prevention and Management

Montana homeowners, gardeners, landscapers, and nursery operators should keep an eye out for Japanese beetles (Popillia japonica). This invasive insect is a serious plant pest that can damage a wide variety of trees, shrubs, flowers, fruits, vegetables, and turfgrass. Japanese beetles have become established in the Billings area, but preventing their spread to new locations remains an important priority for Montana.
