Transcription

1 Fishbeck, Thompson, Carr & Huber, Inc. Battling Invasive Plants: A Brief Overview and Case Study Elise Hansen Tripp 2013 Michigan Watershed Summit

2 Invasive: Alien Species: not native to a particular ecosystem (non-native, exotic, introduced) Cause Harm Economy Environment Human Health Executive Order 13112, 1999 Photo: USFS

3 Negative Effects of Invasives: Environmental Reduce biodiversity and displace rare species Alter hydrologic conditions Alter soil characteristics Alter fire intensity and frequency Interfere with natural succession Compete with pollinators Poison or repel native insects Photo: USFS

4 Negative Effects of Invasives: Economy Serve as a reservoir of plant pathogens Difficult and costly to control Impede industries (fisheries, forestry) and threaten agriculture Overall drain on the economy (estimated in 1998 at $13,000,000,000)

5 Negative Effects of Invasives: Human Health Reservoirs for disease (insects, rodents, birds) Example: West Nile virus in non-native mosquito Food security Water depletion

19 Control: Know the species life cycle!!! Mechanical Pulling, Digging Cutting, Mowing Chemical (herbicide application) Photo: MDEQ On foliage On cut stems or stumps Photo: MDEQ

20 Control: Prescribed Burns Appropriate for prairie/meadow ecosystem to remove woody vegetation Need burn plan and burn permit May stimulate some species Photo: USFS

21 Control: Biological Control Species specific Utilizes natural predators that are introduced Photo: USFS

32 Case Study: Pigeon River Drainage Improvements Notify the neighbors Letters Signage: Notice and Treatment Map

33 Case Study: Pigeon River Drainage Improvements Applied glyphosate and imazapyr in September 2012

34 Case Study: Pigeon River Drainage Improvements

35 Case Study: Pigeon River Drainage Improvements Mowed\cleared dead vegetation in Nov/Dec 2012 Burned thatch

36 Case Study: Pigeon River Drainage Improvements Stockpiled soil/roots in an upland location

37 Case Study: Pigeon River Drainage Improvements

38 Case Study: Pigeon River Drainage Improvements

39 Case Study: Pigeon River Drainage Improvements September 8, 2011 January 17, 2013

40 Case Study: Pigeon River Drainage Improvements Treatment Report, submitted no later than November 30

41 Case Study: Pigeon River Drainage Improvements Lessons Learned A Great Lakes Shoreline Management General Permit was not required for mowing phragmites below the OHWM. Don t staple public notice signs to lathe Aerial application, while expensive, is an effective means of herbicide application
