  1. Use ring-barking (girdling), cutting or silvicides to produce snags

    A before-and-after study in Highland, Scotland (Denny & Summers 1996), found that, by 1994, no crested tits Parus cristatus used any of 30 tree stumps created between 1981 and 1989 to provide nesting habitats. Stumps were made by cutting trees 1-1.2 m from the ground and were supposed to rot to allow tits to excavate nesting sites. Investigating natural nest sites, the authors found that natural nests were both much higher (average of 7.3 m above ground) and in much larger trees (average diameter at breast height of 41 cm vs. 20-26 cm). They also argue that the trees probably needed more time to rot.
