  1. Increase ‘on-the-ground’ protection to reduce unsustainable levels of exploitation

    A before-and-after study in western Costa Rica (Vaughan et al. 2005) found an increase in a scarlet macaw Ara macao population from 185-225 individuals in 1990-4 to 225-265 in 1997-2003, following an increase in anti-poaching patrols and the confiscation of ladders and tree-climbing equipment (used to remove nestlings from nests) and several other interventions (see ‘Use education programmes and local engagement to reduce pressures on species’, ‘Promote sustainable alternative livelihoods based on species’, ‘Provide artificial nesting sites’ and ‘Guard nests to increase nest success’). In 1990-4 the population had been showing a 4%/year decline. In addition, following the start of intensive anti-poaching activities, the young-to-adult ratio (which is related to recruitment rate) was 9% in 1995-6 (compared to an average of 6% for 1990-2003). However, the intensity of the anti-poaching effort could not be maintained and when it was reduced the ratio fell back to 6%.

     

  2. Promote sustainable alternative livelihoods

    A before-and-after study in western Costa Rica (Vaughan et al. 2005) found an increase in a scarlet macaw Ara macao population from 185-225 individuals in 1990-4 to 225-265 in 1997-2003, following the promotion of economic incentives relating to macaws and several other interventions (‘Use education programmes and local engagement to help reduce persecution or exploitation of species’, ‘Provide artificial nesting sites’ and ‘Guard nests to increase nest success’). In 1990-4 the population had been showing a 4%/year decline. This study is discussed in more detail in ‘Increase ‘on-the-ground’ protection to reduce unsustainable levels of exploitation’.

     

  3. Guard nests to increase nest success

    A before-and-after study in western Costa Rica (Vaughan et al. 2005) found an increase in a scarlet macaw Ara macau population from 185-225 individuals in 1990-4 to 225-265 in 1997-2003, following the protection of artificial and natural nesting cavities and several other interventions (see ‘Use education programmes and local engagement to reduce pressures on species’, ‘Promote sustainable alternative livelihoods based on species’, and ‘Provide artificial nesting sites’). In 1990-4 the population had been showing a 4%/year decline. This study is discussed in more detail in ‘Increase ‘on-the-ground’ protection to reduce unsustainable levels of exploitation’.

     

     

  4. Provide artificial nesting sites for parrots

    A before-and-after study in western Costa Rica (Vaughan et al. 2005) found an increase in a scarlet macaw Ara macau population from 185-225 individuals in 1990-4 to 225-265 in 1997-2003, following the provision of artificial nests and several other interventions (see ‘Use education programmes and local engagement to reduce pressures on species’, ‘Promote sustainable alternative livelihoods based on species’, and ‘Guard nests to increase nest success’). In 1990-4 the population had been showing a 4%/year decline. This study is discussed in more detail in ‘Increase ‘on-the-ground’ protection to reduce unsustainable levels of exploitation’.

     

  5. Use education programmes and local engagement to help reduce persecution or exploitation of species

    A before-and-after study in western Costa Rica (Vaughan et al. 2005) found an increase in a scarlet macaw Ara macao population from 185-225 individuals in 1990-4 to 225-265 in 1997-2003, following the formation of a local conservation organisation; environmental education programmes; meetings with local stakeholders and several other interventions (‘Promote sustainable alternative livelihoods based on species’, ‘Provide artificial nesting sites’ and ‘Guard nests to increase nest success’). In 1990-4 the population had been showing a 4%/year decline. This study is discussed in more detail in ‘Increase ‘on-the-ground’ protection to reduce unsustainable levels of exploitation’.
