### When: Saturday, July 20th -- Monday, July 22nd

### Where:  Amherst, Belchertown, and Holyoke, MA

### What:

**DIY Aerial Water Chestnut Assessment**.  [Water Chestnut](http://www.dnr.state.md.us/bay/sav/water_chestnut.asp) is an invasive aquatic plant species in Massachusetts that forms dense, floating mats which severely limit available light and nutrients for aquatic ecosystems.   On Monday, July 22nd, we'll be working with members of the [UMass Amherst Dept of Environmental Conservation](http://eco.umass.edu/) and the [US Fish and Wildlife Service](http://www.fws.gov/) to apply Public Lab's DIY aerial imagery techniques in the assessment one or several management sites near Amherst, MA.   Depending on the conditions, we're planning on using [kites](http://publiclab.org/home#kite-mapping) and/or [balloons](http://publiclab.org/home#balloon-mapping) (perhaps based from canoes) to take aerial photos of affected areas both "before" and "after" a management event.  We'll also be capturing [Infragram](http://publiclab.org/wiki/infragram) near-infrared imagery, in order to see whether near-infrared photography can help to distinguish Water Chestnut from other aquatic species.  

**Weekend mini workshops**.  Although the Water Chestnut aerial imaging event will occur during the day on Monday, July 22nd, we're planning on gathering on **Saturday, July 20th** and **Sunday, July 21st** at the newly-formed "Hacker Farm" in nearby Belchertown, MA in order to do some prior brainstorming, kite and balloon flying, and potluck BBQ-ing, as well as informally introduce:

- [DIY Spectroscopy]
- [DIY Infrared photography]
- [DIY Agriculture]

### Lodging

There is plenty of room to camp at the [Hacker Farm](http://goo.gl/maps/2IH4l) in Belchertown, MA, on Friday, Saturday, Sunday, and Monday nights!
