✍️ Sample PDC Questions & Answers
1. Which documentation practice BEST demonstrates regulatory compliance for PDC certified professionals?
Organized, dated, and signed records demonstrate systematic regulatory compliance.
2. A designer wants to implement a forest garden using a phased approach. Which phase typically comes FIRST?
Pioneer species and soil preparation create the conditions needed for successive plantings, mimicking natural forest succession.
3. In PDC design, what is the purpose of a 'stakeholder consultation' process?
Stakeholder consultation ensures that those who will live with or be affected by a design are heard, increasing both the quality of the design and community ownership of outcomes.
4. What is the ethic of 'Fair Share' in permaculture?
Fair Share, also known as Return of Surplus, is the third core ethic of permaculture. It encourages individuals and communities to distribute any surplus resources or yields equitably and to limit their own consumption to what is truly needed. This ethic aims to ensure that everyone has access to resources and that the planet's capacity is not overexploited, promoting social and ecological justice.
5. The permaculture principle 'Use small and slow solutions' cautions against which common design mistake?
Small and slow solutions allow designers to observe, learn, and adjust before committing large amounts of energy, money, or land to unproven approaches.
6. In designing a food forest on a sloped site, where should water-loving trees like willows or alders ideally be planted?
Water-loving species perform best where water naturally accumulates—at slope bases and drainage channels—reducing irrigation needs.
