Dear Angela and listmembers,
I know of some Dutch examples, although not from the first hand,
as all were created with the help of members of BIAX Consult.
In several cases, hedges of Buxus sempervirens were used to
follow the contours of subsoil remains of buildings. The buildings
were of stone, and good to be traced by non-destructive
methods (conductivity measurements). Buxus was preferred
because of its shallow rooting depth, so that the remains would
not be disturbed by penetrating roots.
In one other case, higher trees were needed to create the
desired effect. In that case, the trees were planted according
to the contours of a building, but NOT directly above the
archaeological remains, but at some distance.
In many other cases, for instance on burrial mounds, the (natural)
tree cover is often removed because of the disastrous effect
of their roots. Anti-rooting mats are then sometimes applied to
prevent new penetration of the archaeological layers. Such
mats could also be used in cases of visualisation, as they will
prevent to a certain degree that roots will reach the archaeological
remains.
In one case I dealt with myself, a longer strech of land along the
new TGV/HSL railway with several sites in the subsoil was planted.
At first, the engineers had selected Fagus sylvatica that had
to form a kind of hedge, but I consulted some specialists and
concluded that Acer campestre should be preferred, because
it roots less deep and besides the fallen leaves are much better
converted to humus, which will result in less leaching of the
soil, which was considered positive for the archaeological
remains. So if Buxus is too low to create the desired effect, it
might be considered to plant Acer campestre, maybe in combination
with a anti-root mat in the soil above the archaeological remains.
Maybe the beloved Prunus spinosa might also be useful ;-))))
Best wishes and a fruitful 2005 to everyone!

Dear all,
does anybody know about a place or site, where living trees or shrubs
ware planted to mark archaeological structures hidden in the soil??
To visualize ancient streets or houses etc?? And if yes, which trees
or shrubs have been planted??
Happy New Year to all of you and I am greatful for ideas and
information!!
best wishes
Angela
