2. Razlika između stvarnih drvnih zaliha poslije sječe i Surićevih minimalnih
zaliha je u G. J. Ravna Gora na toplim ekspozicijama znatna
(14,6%), pa bi Šurićeve minimalne zalihe kod primjene na toplim ekspozicijama
trebalo povisiti za cea 15%.
3. Neophodno su potrebna daljnja sistematska istraživanja minimalnih
zaliha, i njihovo ustanovljenje za svaku gospodarsku jedinicu, šumski predjel
ili odjel. Radi ustanovljivanja istih potrebno je temeljito poznavanje
prirasta, te utjecanja visine zalihe na istog, i to kroz duži period vremena.
A CONTRIBUTION TO THE DETERMINATION OF MINIMUM VOLUME OF THE
STANDING CROP AFTER CUTTING IN THE SELECTION FOREST


1. Difference between the actual volume of the standing crop after cutting and
the Surić´s minimum volumes of standing crop is not high in the management unit of
»Ravna Gora« on cold slopes, and it amounts to 3,1 respectively 5,4´%>. But these relatively
low volumes of the growing stock produce also a low yield, and that is why
they should be increased.
2. The same difference as under point 1. is considerable on warm slopes (14,9´/o),
and therefore Surić´s minimum volumes of standing crop when applied to warm slopes
should be increased by ca. 15%.
3. Necessary are further systematic investigations into the minimum volumes of
the standing crop as well as äheir establishing for each management unit, forest district
and compartment. In order to establish this it is necessary a thorough knowledge of
the increment and of the influence of standing crop on the increment for a longer
period.
