Morphology
The compound combines 'nurse' (to care for or nurture) with 'log' (a tree trunk), so the basic idea of a log that nurtures or supports new growth is inferable from the parts. However, the ecological, specialist use of 'nurse log' and the metaphorical extension of 'nurse' to a piece of dead wood make the sense somewhat domain-specific rather than fully transparent to an average B1 learner without context.
Etymology
Nurse log is a name for a fallen log where the old tree acts like a nurse, giving young plants and fungi food, moisture and a safe place to grow. So the image of a dead tree 'caring for new life' explains why the name means 'a decaying trunk that helps new plants grow'.
