Effects of a Severe Typhoon on Forest Dynamics in a Warm-temperate Evergreen Broad-leaved Forest in Southwestern Japan

Satoshi Saito Journal of Forest Research 2002. doi:10.1007/bf02762602

Other claims from this paper (11)

Observation The return period of typhoons over 30 ms−1 was estimated at 2.2 years.
Observation The return period of T9313 was estimated at 104.5 years.
Observation T9313 damaged approximately 10% of all stems.

Observation Distylium racemosum showed little stem decrease and recruitment.
Observation Cinnamomum japonicum showed a large stem decrease and much recruitment.
Observation Eurya japonica showed less stem decrease than recruitment.
Observation Climax species showed a blunt short-term response.
Observation Few-sapling species showed a retreat short-term response.
Observation Light-demanding and sub-canopy types showed multiple short-term responses.

Other claims from this paper (6)

Observation Ground vegetation deterioration appeared unavoidable at camping sites in Southern Finland.
Observation Only a few grass species tolerated heavy trampling.
Intervention effect Vegetation deterioration was moderate below 10,00015,000 user days.
Intervention effect Ground cover was completely destroyed above 100,000 user days.
Association Destruction of ground vegetation was associated with an abrupt, persistent decrease in tree radial growth.
Intervention effect After ten years of use, tree growth in trampled areas was 35% lower than in untrampled areas.
