Nature notes


Sun 8th forestry few Redwing and Fieldfare (latter heard only); some Bats still driving back at dusk.


Mild first half to November, modest fresh grass growth, some fresh leafing to hedges and shrubs, a few flowers inc Primroses in back garden.


Mid month a few Buttercup in flower on the lawn and plenty of daises.


Sat 21st a wasp about the Holly tree, still no proper frost.


Late month still rather mild although had a -3c; fresh growth quite prolific grass, mosses, ferns, shrubs, Hazel buds swelling; various flowering especially some garden shrubbery and roses even.


Psilocybe Semilanceata mushrooms (few) front lawn late month not seen these for a few years in this location.


Sun 29th nice and sunny, walked along Neuadd lane where prolific fresh foliage, inc ferns, Foxgloves and Celandines, while some grasses have attained full height and seeds for second time this year; a few fresh Oak leaves, some Hazel leaves have come out anew also a few Blackthorn leaves, while where the hedges were trimmed (may be a month or so back) Wild Roses have sprouted a foot or more above the hedgelines; even one Blackberry in flower adjacent to some fresh berries by the farm! Red Campion flowers and a few of various other flower spp; nettles having fresh green leaves - all in all rare to see this level of re-growth at the very end of November and such a contrast to the damaging May frosts along this lane 6 months ago. Plentiful swarms of gnats and small flies too.


Mon 30th Daffodil spikes up just along road in the spot where always early and were out Christmas 2015!
