Distribution Maps Please add your sightings!

We are attempting to map the infestations of various invasive plants.  Here are the links:

Anyone can add a record of an infestation.  Each map has three layers.  Use the check boxes on the left of the legend in each map to show or hide each.  

Distribution map 1

Angelica, Japanese Knotweed, and Loosestrife

Distribution map 2

Japanese barberry, Bishop's weed, Moneywort

Distribution map 3
Giant Hogweed, Poison Ivy, Goutweed

Distribution map 4 

Sweet clover, Multiflora rose, Rugosa rose

Please help!  This is a collaborative effort.  Add your sightings. We want to get at least the date, the size of the infestation, and any attempts to do anything about it or comments on how it started or changes it is making on other plant communities.


Descriptors: 
Colonizer- 1 plant on its own, no seedlings beneath it
Clump-big enough to create shade underneath
Linear-plants are arranged along a line, such as a ditch
Diffuse-there are no definable edges to the patch
Clear-the patch is clearly localized

Small-an area less than 3 metres across
Medium-an area less than 10 metres across
Large-larger than 10 meters

For removal methods, use percentages for each method, ie:
30% pulled, 30% cut to ground, 20% left standing, 20% flowers removed.

It would be good to note the ages of seedlings as well.  First year (1Y):  

Young plants (YP): 

Next year (NY):  Two or more mature leaves
This year bud (TYB): Bloom stalk forming
This year flowering (TYF): In bloom 
Pollinated (TYP): 

Mature seeds (TYS): Tan and falling off the plant
