15 The Monarch Larva Monitoring Project

16 MLMP Training

17

18 MLMP Protocol Volunteer and Choose a Site  Gardens, parks, roadsides, prairies (need milkweed) Site Description  Location, size, type  Milkweed species and density Weekly Monitoring (2-3 hours)  Estimate monarch densities  Quantify milkweed quality  Estimate parasitism rates  Track weather conditions

19 Past and Current Monitoring Locations as of Summer 2003

21 Annual Variation in Egg densities: Upper Midwest

22 Maximum eggs/milkweed Egg densities: Upper Midwest

23 Survival Total # of 5ths Total # eggs approximate measure of survival from egg to 5 th instar =

24

25 Upper Midwest Survival (# of eggs on bars) # 5 th instars/# eggs

26 Tachinid Fly Parasitism

27 Upper Midwest Rates 2003 Rates in 2 Regions Proportion Parasitized

28 MLMP Extensions Monarchs and genetically modified crops (Bt corn and herbicide tolerant soybeans) Potential effects of climate change Impacts of land use changes Impacts of pesticides Impacts of environmental perturbations

29 Impacts of Environmental Perturbations January 2002 Mexico Storm

30 Maximum eggs/milkweed Egg densities: Upper Midwest

31 Key Motivators “My work may help promote monarch conservation” “My work is leading to increased understanding of monarch biology” “I am involved in real scientific research”

32 Scientific Outcomes Much can be learned from basic distribution and abundance data In addition, data can  provide direction for experimental and theoretical research  inform public policy and conservation efforts

33 Thanks!! MLMP volunteers throughout US and Canada, students Michelles Solensky and Prysby, Sonia Altizer, Liz Goehring, Jolene Lushine and many more NSF, Monarchs in the Classroom, and the Xerces Society
