Coniferiporia weirii

Summary of the Express Pest Risk Analysis for Coniferiporia weirii

PRA area: Poland

Describe the endangered area: The entire PRA area

Main conclusion

Coniferiporia weirii occurs in patches or centres of infection mostly as root rot. Pathogen may infect many conifer species in Europe. The main host plant is Pseudotsuga menziesii. Coast Douglas-fir occurs only in Pomerania and constitutes a relatively low proportion of mixed stands. C. weirii has A1 quarantine status for EPPOs. Fungus introduction and spread is prohibited in Europe. The most likely way of entry is import of infested seedlings, infected raw timber, logs, bark. Natural dispersal occurs slowly. The disease is hard to detect, because symptoms become apparent when the root system is in an advanced stage of deterioration. C. weirii is native North America, Japan and China species. The fungus may appear in PRA area, in case of similar climatic conditions.

Rating of the likelihood of entry: Low

Rating of the likelihood of establishment outdoors and in protected conditions: High

Rating of the likelihood of spread: Low (The main host plants are introduced and rarely grow in Poland. However C. weirii may infect many conifer species in EPPO region)

The most important phytosanitary measure is monitoring of imported plant material and wood from area where fungus occurs.

It is necessary to prepare strategies and eradication measures in case of fungus occurance in PRA area.

Dendrolimus sibiricus

Summary of the Express Pest Risk Analysis for Dendrolimus sibiricus

PRA area: Poland

Describe the endangered area: mixed and pure stands of conifers

Main conclusions

White-lined silk moth presents a potential risk for forests in PRA area. Considering climatic conditions and the fact that conifers are commonly (almost 70% of trees) in Poland it is expected that pest will be able to establish and spread in PRA area.

If environmental resistance will be insufficient there is possibility of progressively establishment and forest damage.

All of phytosanitary measures and eradication methods should be used in case of pest occurrence in PRA area. Import of wood material is prohibited from non European countries so this way of entry is insignificant.

Wood or plants with larvae or eggs of D.sibiricus need to be destroy.
