Thanks Peter,
    Perceived loss may depend upon the time frame involved and the =
specific area. According to =
http://www.wildlifetrusts.org/wildlife/habitats/hedgerows
some 121,000 km of hedgerows had been lost in the UK by the 1990.=20
    This may be small or large relative to the total remaining; not =
sure.

    I would expect the impact of habitat shrinkage on a population to =
frequently be delayed until some other factor, e.g. adverse weather, =
caused a dramatic decline in numbers. In such circumstances, sparse =
habitat, could readily preclude recovery.=20

    Yt, Dave Webster, Kentville

  In our frequent visits to the UK we haven't noticed much decline in =
hedgerows, probably because there are quite strict regulation governing =
their removal

    Hi Steve & All,                            Dec 16, 2015
        It seems odd that there was no mention of the obvious; loss of =
hedgerows by consolidation of fields and crop specialization which would =
surely imply for some species not only loss of habitat but habitat =
fragmentation.=20

      Continuing an earlier thread, this short Guardian article =
summarizes a robust increase in a few, but drastic decline in many =
species, in UK.  Causes unknown but pesticides and climate change among =
suspects fingered. =20
