Participate in the New Monarch Watch Citizen Scientist Project
INSTRUCTIONS FOR CITIZEN SCIENTISTS
Here is what we need you, as citizen scientists, to do:
1. Register as a participant in this project by providing your name, location (including latitude and longitude), and email address via the form at http://monarchwatch.org/register
To determine your geographic coordinates, please use any of the following sites (or others) to enter your city, state/province, and zip/postal code and retrieve your latitude and longitude in decimal form (e.g., latitude: 38.95 longitude: -95.27 for Lawrence, KS 66045).
Why do we need a “monarch calendar” and your help recording monarch numbers?
The decline in monarch numbers over the last 15 years has inspired numerous attempts to define critical factors that explain the inter-annual variation in monarch numbers. The data sets used for these analyses have had a variety of limitations which have either been ignored or underappreciated by the authors of a number of publications. The truth is that much of the data that is available is too general and does not adequately represent important aspects of the biology that underlies the development of the population each reproductive season.
There are numerous gaps in our knowledge and some of these gaps can be addressed if we can convince a large number of monarch enthusiasts (citizen scientists) to record the number of monarchs they see each day and what the monarchs are doing, along with general information about the physical conditions associated with each observation.
At the start of this project, we won’t ask participants to record behavior or physical conditions (temperatures and wind speed and direction) but a few observations and notes along those lines might be useful in targeting conditions most favorable for monarch activity. The pivotal latitude is 35N (e.g., Oklahoma City). If the observer is located at a latitude less than 35N (i.e., “South”), we need the number of monarchs seen each day during the following two periods: 10 Mar-30 Apr and 1 Aug-25 Sep – 52 days & 56 days = 108 days total. If the observer is located at a latitude greater than 35N (i.e., “North”) the observation periods are 1 Apr-10 Jun and 15 Jul-20 Aug – 71 days & 37 days = 108 days total.
The first period in the south covers the interval during which the overwintering monarchs arrive in Texas and Oklahoma and points to the east. We need to capture a better estimate of the number of monarchs in this region that arrive from Mexico each year. This starting number has not been captured effectively. The second interval in the south captures the arrival of pre-migration monarchs from the north as well as potential local reproduction during this time. In the north, the first interval will capture some of the returning monarchs early in that period but is more likely to chronicle the arrival of first generation monarchs migrating north to the summer breeding grounds. The second period in the north should capture the relative intensity of the reproductive activities of monarchs during the period in which most of the eggs are laid that become the adults that populate the migratory generation later in August and September.
