    Protection of spruce seedlings against pine weevil attacks by treatment of seeds or seedlings with nicotinamide, nicotinic acid and jasmonic acid2016In: Forestry (London), ISSN 0015-752X, E-ISSN 1464-3626, Vol. 89, no 2, p. 127-135Article in journal (Refereed)
    Abstract [en]

    Sustainable methods are required to protect newly planted tree seedlings from insect herbivore attack. To this end, here Norway spruce (Picea abies (L.) Karst.) seeds were treated with 2.5 mM nicotinamide (NIC), 2.5 mM nicotinic acid (NIA), 3 mM jasmonic acid (JA) or 0.2 mM 5-azacytidine (5-Aza), and 6-month-old seedlings grown from these seeds were planted at a reforestation area in central Sweden. Attack by pine weevils (Hylobius abietis) was reduced by 50 per cent by NIC treatment, 62.5 per cent by JA treatment and 25 per cent by 5-Aza treatment, when compared with seedlings grown from untreated seeds. Watering 18-month-old spruce seedlings with 2 mM NIC or 2 mM NIA did reduce attack during the first season in the field by 40 and 53 per cent, respectively, compared with untreated plants. Girdling was also reduced by the different treatments. Analysis of conifer seedlings treated with 5-Aza points at a possible involvement of epigenetic mechanisms in this defensive capacity. This is supported by a reduced level of DNA methylation in the needles of young spruce seedlings grown in a greenhouse from NIC-treated seeds. Seed treatment for seedling defense potentiation is simple, inexpensive and also a new approach for forestry with many potential applications.

    Contingent Valuationof the Natura 2000 Nature Conservation Program in Finland2000In: Forestry (London), ISSN 0015-752X, E-ISSN 1464-3626, Vol. 73, no 2, p. 119-128Article in journal (Refereed)
    Abstract [en]

    This paper shows how contingent valuation studies can produce relevant information for public nature conservation decisions. The study analyses the preferences of Finnish households for a nature conservation programme, Natura 2000 Network, by applying a dichotomous choice referendum model of the contingent valuation survey. In order to study the influence of attitudes and beliefs on a choice between the status quo and the new conservation project, an attitude-behaviour framework is applied. Beliefs concerning the outcomes of the nature conservation policy and evaluations of their importance describe how attitudes towards the programme are formed. The choices in the referendum are explained using a logit regression model and are found to be a function of attitude and socio-economic variables. The probability of a person supporting the proposed conservation level depends significantly on the income, age and background (urban-rural) of the respondent. The estimated model of choice behaviour is used to calculate the average willingness to pay for the Natura 2000 Network, which is also compared to the costs of the conservation programme.
