Hirvlaste põhjustatud metsakahjustused on olnud oluliseks probleemiks metsakasvatusele
Eestis. Käesoleva uurimuse eesmärk on anda ülevaade ulukikahjustuste ennetamise ja
vähendamise võimalustest. Selleks üldistati asjakohaseid kirjandusandmeid ja katsetati hiljuti
turule ilmunud repellendi „Trico“ efektiivsust. Välitööde käigus töödeldi 2013 a. sügisel
repellendiga proovitükid seitsmes potentsiaalselt ulukite poolt ohustatud metsakultuuris.
Kevadisel metsakultuuride inventeerimisel selgus, et „Tricoga“ töödeldud männi- ja
kuusetaimi ei olnud hirvlased talveperioodil kahjustanud. Ka kontrollaladel täheldati vaid
üksikuid kahjustusi, mistõttu olulist erinevust võrreldud alade kahjustatuses ei täheldatud.
Ulukipeletusvahendi „Trico“ efektiivsus erinevates tingimustes vajab kindlasti edasist
uurimist.
Wildlife damage caused by cervidae has been a major problem for silviculture in Estonia. The purpose of current study is to give an overview of various means, that can be used to avoid or limit wildlife damage, among other things the effect of a new animal repellent “Trico” was tested. The data from previous studies and fieldwork were used in this research. The fieldwork was performed in autumn of 2013 by spraying the repellent in seven young forest stand by strips. During the evaluation in the spring, it appeared that there was no wildlife damage in the “Trico” treated area. Little damage was observed in control area, therefore no significant difference was found between the compared areas. The effectiveness of the animal repellent „Trico“ definetly needs further research in different conditions.
