Though there is a certification system in place for the more common native trees and shrubs, there are a number of challenges facing landscape practitioners, not least the absence of a certification system for Irish native provenance grass and wildflower seed mixes. The development of a scheme is a challenge for the Irish landscape community. Until such time as this is achieved, foreign provenance native and non-native grass and wildflower seed mixes will continue to be used on road schemes, in urban parks, private gardens and wildlife gardens in schools.
Furthermore, there is no certification system for wetland marsh (GM1) plants, e.g. Yellow Flag (Iris pseudacorus), and heath (HH) plants, and these species continue to be specified in landscape design plans. There are also a number of uncertified woodland species such as bird cherry (Prunus avium), purple willow (Salix purpurea), Dog rose (Rosa canina), honeysuckle (Lonicera periclymenum), broom (Cytisus scoparius) and ivy (Hedera hibernica) which are not listed under the NWS. Recently, the availability of spindle (Euonymous europaeus) and guelder rose (Viburnum opulus) has declined due to lack of demand for Irish provenance plant material.
It is expected that this website will raise public awareness and environmental education as to the value of native species and highlight growing societal concerns in relation to the use of Irish provenance native plant material. In this regard, it is hoped that this will subsequently increase market demand for Irish provenance native plant material, which in turn should ensure continuity of supply into the future.
