Milkweed Plots Survey


We are interested in where milkweed  is growing because it is the only food source of the Monarch butterfly. We would like to be able to monitor where the Monarch is breeding and learn if the population is healthy.  If you would like to help please use some of the forms here. You can send your results to

. You can help by just driving, walking, or biking you local area and reporting any milkweed you observe growing there. In the Fall, milkweed has very identifiable seed pods to help recognize the plants.  If you do find some plots, we would like to know. The following is the desired information

  1. location (so it can be monitored next summer for Monarchs)
  2. type of milkweed
  3. size of the patch
  4. short description of the habitat it is growing in and growing next to.
  5. your name and contact information

Milkweed will next be visible in May  when it will be sprouting up from the ground. It will be flowering in June-July.

Identifying Milkweed

Common Milkweed plot in November

Wikipedia has a good description on its  Common Milkweed Page.  This is the most abundant type of milkweed and grows in patches because is spreads through an expanding root system. It can fill whole fields, usually fallow or abandoned fields.  It is common along hedgerows and along roadsides and especially along the railbed that runs through the centre of the Annapolis Valley. It likes light soils and thus is abundant in the Cambridge and Waterville areas. In the Fall and Winter the milkweed plants can be easily identified from the prominent seed pods and seed fluff that may be still be attached to the pods. The stalks are tough remain after the leaves drop after a frost.

There is also a Wikipedia Swamp Milkweed page.

Swamp milkweed will grow in wetter soils and is usually associated with headwaters of streams or their intervales.  It is seen more commonly on the South Mountain and less so in the Valley. However, it can grow anywhere. It is a tall plant but has smaller leaves than the Common milkweed.

Section Maps of Kings County

Below is an index of road maps to use for marking where milkweed patches have been found. Links to the individual maps are beside the map. The maps are drerived from a Kings County road map and are all printable from the pdf file.
