Harvesting Phragmites Reed grass stems from the Marsh for Mason Bee Homes..

I was fortunate to have on our property, a brackish water estuarine marsh in which grows the native Phragmites sp. reed grass.

See this file on the Gooch creek swamp which tells the story of how I had to “save” the Reed Grass beds from extirpation by the BC Forest Lands and Natural Resources Department: (FLNRO)phragmiteskalleFrom Phragmites australis (Cav.) Trin. ex Steud. subsp. americanus I get the hollow tubes that I use for the mason bee homes. This is what they look like in late summer.

At this stage it is too early to cut the stems. That is best done in February

 

In about 1 in 20 plants, the stems  are the ideal size for Mason Bees.

The tubes are cut in the early spring from the lower 1 metre of the stems.

The internode lengths range from 15 cm. to 30 cm .  I select only those sections with an adequate tube diameter. 5/16 ” diameter is ideal.

Since this reed grass is not generally available, it is easiest to sandwich small plates  of wood with 5/16″ channels routered or sawn into them . There are many references on the internet that show how to do this.

See this post on Harvesting and Cleaning the Mason Bees in the fall.

Phragmites australis subsp. americanus: the native reed grass on Vancouver Island

NOTE: I have updated this 2015 post in order to make it appear closer to the other mason bee information.

You will find many articles on the internet about the invasive species of Phragmites but the one that grows here on Vancouver Island is the Native species, Phragmites australis (Cav.) Trin. ex Steud. subsp. americanus. 

The following article on the Metchosin Coastal website describes an example of  misidentification of this species in British Columbia. titled:

Put Out Your Mason Bees when Pollinators are Needed

NOTE: I have updated this 2016 post in order to make it appear closer to the other mason bee information

The time to put out your mason bees which have been overwintered in your refrigerator is when you need them to do their work. I release mine in batches.  The first batch was several weeks ago when the peaches and nectarines were in bloom. This week, the pears, plums and cherries are in bloom so I just put out  another batch of cocoons near my bee homes. I will save the last batch for my apple trees which bloom later.

2016-03-31 peachI had to transplant this peach tree this year to the corner of the vegetable preparation building so I found another good spot to place a bee home.

Phragmites Reeds for Mason Bee tubes

Phragmites in estuary/marsh
Last years stems of Phragmites in estuary/marsh being harvested for mason bee tubes. It is important that this is done only before new shoots start to emerge.  I have a theory that this native Phragmites exists in this marsh only because the marsh was fenced in the early years to prevent grazing by cattle and sheep. It has been eliminated from most of the other marshes in BC by grazing (personal communication with Robert Prescott-Allen). The reason this marsh was fenced was that the plant Triglochin maritima  (Sea arrow grass) grows in the marsh and it is toxic to grazers.

(http://metchosinmarine.ca/gf/triglochin-maritima/)

“Seaside arrow-grass (Triglochin maritima) is a native plant found sporadically across Canada in saline, brackish, or fresh marshes and shores. This plant contains cyanogenic glycosides, which can release HCN during mastication by animals. Poisoning occurs primarily with ruminants, including cattle and sheep. The concentration of toxic chemicals increases during times of moisture depletion (Majak et al. 1980, Cooper and Johnson 1984, Poulton 1989).”

I have been posting my photos of different species I have encountered on the iNaturalist website.  Many are species I have found here in the Metchosin Community.
