  6. Hi Fungus is Guignardia aesculi present in the UK, I was totally unaware this leaf spot even existed? regards Dave
  7. Been reading that the Small tortoiseshell butterfly has been in decline for many years, which was not something i had personally noticed as there always seemed to be an abundance of them on site. I just literally had one of those sudden gestaltist moments and realised i have not seen a single one this year:thumbdown: has anyone else noticed such a terminal decline or is this section of Lincolnshire unusual (Biologically speaking of cause) Dave
  8. Thanks Brushcutter, I now have a copy and everything i needs right there:thumbup: thanks mutchly Dave
  9. The conatations of leaving the dog alive that did this to your brother does not bear thinking about...imagine if a child does the same thing next week (heaven forbid) your brother may have crossed its territory but that is no excuse, especially when the animal is obviously dangerous? i hope your brother regains his previous good looks if not he will certainly be the intresting type.best wishes for a full and speedy recovery. regards Dave
  10. Hi folks is it still possible to obtain forestry commision booklet 39 (timber tariff charts) checked out the FC's site and there is little reference to it is there now a more up to date method of achiving the same end?? regards Dave:thumbup:
  11. Hi Mike we have had similar damage at uni; larger trees survived, suppose because they had larger food reserves in their root system? I have seen bridge grafting used to save valuable trees in the past, this can work well to allow food to be transfered across the damaged section of trunk but can look unsightly...depends on how much the owner wants to retain the tree??? Dave
  12. I'm far from being as well educated as the rest of you guys but like to think i'm pro active, i completely agree with hamadryads opinion Surely it is our responsibilty to nurture the remaining "primary" natural habitats of this planet...once the natural balance is lost it is gone forever along with all the undiscovered evolutionary interactions and synergy? as for Gerrits exeptional posts and honesty all I can say, for me he ranks up there with other inspirational persons listed by members of this forum..truely awesome thread and a great read, thanks fellas Dave:thumbup:

  22. Pteridium is dangerous stuff....dont know if what you are experiencing is an allergic reaction to plant material impregnated in your gloves?? check out the following link for more info Biological Flora of the British Isles: Pteridium aquilinum (L.) Kuhn - MARRS - 2006 - Journal of Ecology - Wiley Online Library the following is taken straight off the site: For humans the health significance of Pteridium poisoning is potentially considerable. In Japan, Brazil, and across northern America (especially the Appalachians), Pteridium is consumed as the developing frond, i.e. the crozier or ‘fiddlehead’ (Fig. 7f). At this developmental stage the quantities of toxin are at a maximum, and in Japan there is the highest incidence of gastric tumours in the world (Evans 1976a; Marlière et al. 2000). High levels of gastric cancers have been identified in other areas where there are large Pteridium infestations, e.g. Costa Rica and North Wales (Buckley 1989; Villalobos-Salazar et al. 1989), although transfer pathways and causal relationships have not been proven. Some effects can be transmitted experimentally via milk (Evans et al. 1972; Villalobos-Salazar et al. 1990; Alonso-Amelot et al. 2000). Transfer to humans through drinking water has also been investigated, and although water soluble extracts of Pteridium contain carcinogens, Galpin & Smith (1986) thought this is not a major cause for concern. However, more recently Rasmussen et al. (2003a,b) has detected ptaquiloside throughout the plant–soil system in Denmark (e.g. 108–3795 µg g−1 in fronds, 213–2145 µg g−1 in rhizomes, 200–8500 µg g−1 in soil solutions). This chemical is water soluble and easily leached from fronds and they estimated a flux of 260 mg m−2 transferred to soils. These fluxes were considered a potential risk for the contamination of groundwater supplies, especially on sandy soils. regards Dave
  23. Great vid think i've got a photograph of his brother ??
