Requirements:
We are looking for a supplier who would be interested in a contract supplying weekly deliveries of leafy branches between the months of May and October. We are looking for a weekly load of approx. 300 branches, 2-2.5m long, with the outlook of potentially a larger amount depending on circumstances year on year but this will be discussed and confirmed before the new season starts.
We have restricted access in terms of vehicle size due to the layout of the road where the material would need to be dropped off. Details of vehicle size limitations can be obtained. The supplier would be expected to offload the material into containers provided by the zoo.
Unfortunately, we have restrictions on what species we can receive due to animals’ sensitivities to the various secondary metabolites and plant toxins. Species preference is given below:
No limits to amounts – can be whole delivery |
No more than 50% – must be mixed with other species |
No more than 25% – must be mixed with other species |
Field maple (Acer campestre) |
Salix spp. (willow) |
Tilia spp. (lime) |
Norway maple (Acer platanoides) |
Betulus spp. (birch) |
Sycamore (Acer pseudoplatanus) |
Common hazel (Corylus avellana) |
Populus spp. (poplar and aspen) |
Horse Chestnut (Aesculus hippocastanum) |
Hornbeam (Carpinus betulus) |
Malus spp. (apple) |
Indian Horse Chestnut (Aesculus indica),/td> |
European beech (Fagus sylvatica) |
Sweet chestnut (Castanea sativa) |
Wild cherry (Prunus avium) |
Ulmus spp. (elm) |
Morus spp. (mulberry) |
Purple plum (Prunus cerasifera) |
|
|
Common dogwood (Cornus sanguinea) |
|
|
Tree cotoneaster (Cotoneaster frigidus) |
|
|
Crataegus spp. (hawthorn) |
|
|

|
|
Common whitebeam (Sorbus aria) |
|
|
Alnus spp. (alder) |
|
|
Wild and domestic plum (Prunus domestica) |
However, if any are working with Short Rotation Coppice, fx for biofuels or firewood, we would be equally interested and we can ask the other supplier not to provide the species produced.
We would be looking at a start up for the season 2020 but would love to meet up during this season and discuss further.
We would be able to offer a payment according to agreement but any donations are of course more than welcome!
If any are interested in donating material ad hoc, we would of course also be interested and we can discuss collection if not practical to drop off.
