Strathrory Burn – 12 September 2015

Monday, September 14th, 2015


The Tain & District Field Club enjoyed the prospect of beating the forecast rain while searching for wolf spiders along the sandy / gravelly banks of this burn. The forecast proved about right so it was wet weather gear all-round, but the specific target species Arctosa cinerea did not appear. Of course, lack of evidence does not provide evidence of non-existence, so future searches may be worthwhile.

TDFC members, as ever, observed and recorded many species which will add to the known assemblage in our area.

Here is a species list :

Moonwort, Botrychium lunaria

Monday, May 19th, 2014

Moonwort, Botrychium lunaria, is presently abundant on Nigg dunes, as seen by David.

If you haven’t seen Moonwort (Botrychium lunaria) the small grassland fern, it is present in profusion at Nigg dunes at the moment (NH 802 689).
It is easiest to find along the edges of the path in the slightly loner grass areas.

2014 Aspen Catkins

Tuesday, April 15th, 2014

It is not since 2010 that breeding Aspen has been seen locally – SEE HERE.  On April 14, 2014 a single Aspen was seen near Ardgay with a good display of male catkins.

There are many Aspen stems in the area but none other than this one show any sign of catkin flowers.  It may be time to start noting whether any other Aspen will flower this year.

April 19; about 200m away from the Aspen stem above another showed signs of catkins (photo below).  These are female flowers and are so far restricted to only a few upper branches.

Aspen Catkins – male or female?

Sunday, May 16th, 2010

Remember 9th of March when John Parrott spoke about aspen?

On 16th May Marion & Phil spotted a single aspen tree with catkins in a collection of over 60 ramets (stems) mixed with birch, scots pine and alder.  This ratio may be in line with the rarity of Aspen setting seed.

The only branches showing catkins were quite high up and digiscoping was resorted to in order to get images.

North Highland Forest Trust has information HERE, from which I have purloined these images.

I will try to watch the catkins develop to ascertain which sex they are.

To confirm which catkin is which sex NHFT advice is to break off a small branch/twig, place it in water so it survives, and watch the catkins develop.

The location of this aspen tree is NH 59692 89843, +/- 7metres, so says the GPS.

That is above Ardgay, Sutherland on Landranger sheet 21.
