Abstract
V gozdnem rezervatu Repiško smo naredili ponovno premerbo dreves na sistematičnih vzorčnih ploskvah iz leta 2014, ki jih je postavila Ana Brglez. Na vzorčnih ploskvah smo premerili vsa drevesa z merskim pragom 5 cm, jim izmerili prsni premer ter določili drevesno vrsto in stanje. Znotraj teh ploskev smo si začrtali še manjše ploskve, na katerih smo popisali vse mladje in določili drevesno vrsto in stopnjo objedenosti. Po analizi smo ugotovili, da večjih sprememb v primerjavi z letom 2014 ni bilo. V letu 2014 je bila gostota 663 dreves /ha, v letu 2022 pa 622 dreves /ha. Drevesna sestava je ostala skoraj nespremenjena, večjo razliko smo zabeležili le pri navadnem jesenu, ki je bil okužen z jesenovim ožigom. Iz izračunov smo ugotovili, da se je delež bukve v skupni lesni zalogi zmanjšal zgolj za 1 %. Delež ostankov odmrlega drevja na ploskvi je ostal skoraj nespremenjen, saj se je v letu 2022 povečal za samo 1 %. Večjo razliko smo opazili pri gostoti mladja, ki je leta 2014 štela 13.600 osebkov/ha, leta 2022 je številka upadla na 10.500 osebkov/ha. Leta 2014 smo imeli 9-% objedenost osebkov, leta 2022 pa 21-%. Na koncu smo si začrtali še ploskev za popis odmrle lesne biomase, kjer smo ugotovili, da se je vrednost znižala iz 150,7 m3/ha leta 2014 na 117 m3/ha leta 2022.

Title:Stand development in Repiško forest reserve
Abstract:
In the Repiško Forest Reserve, we remeasured all trees in the systematic sampling plots established by Ana Brglez in 2014. All trees in sampling plots were measured using the measurement limit of 5 centimetres. We determined each tree’s diameter, as well as its species and condition. Within these plots, we outlined smaller plots, where we listed all saplings and determined their tree species and the degree of browsing. The analysis detected no significant change compared to 2014. In 2014, tree density was 663 trees/ha, while in 2022, it was 622 trees/ha. The tree species composition remained almost unaltered. The only significant change has been noticed with the common ash that was infected by ash dieback. The calculations determined that the percentage of beech in growing stock has been reduced by only 1%. The percentage of dead tree residues on plots was almost unaltered, as it increased by only 1% by 2022. A greater difference was observed in sampling density, where 13,600 samples/ha in 2014 have been reduced to 10,500 samples/ha in 2022. The browsing on samples has increased from 9% to 21%. Finally, we outlined the plot for the inventory of dead wood biomass that showed a lowered value of 117 m3/ha by 2022 in comparison to the 150,7 m3/ha from 2014.

Keywords:Forest reserve, resurvey, dead woody biomass, sample plots, rejuvenation, analyses.
