TreeYo Permaculture Design Course Handbook is an English-language handbook-style learning website built around the Permaculture Design Course (PDC). It says its content corresponds to the 14 chapters of Bill Mollison’s Designer’s Manual, with four additional chapters drawn from its own PDC. It is positioned not as a standalone video course, but as a mixed-media resource that can be used alongside courses, trainings, or self-study.
Based on the crawled content, the course/resource focuses on the worldview, ethics, principles, pattern recognition, design process, and practical case studies of permaculture. Chapters include Introduction, TreeYo Permaculture Definition, Permaculture Ethics, Permaculture as Design, State of the World, and more. The material emphasizes the transition from philosophy to action, and from ecosystem patterns to site design. The teaching language is English, and the text is fairly dense, leaning more toward theoretical explanation combined with narratives from practical experience.
The site was founded and curated by Doug Crouch. According to the text, he has been practicing permaculture full-time since 2005 and has international teaching experience across different ecological and social contexts, including the Iberian Mediterranean, the dry tropics of India, the highlands of Argentina, Slovakia, and Kentucky. He is currently based mainly in Petersburg, Kentucky, USA, where he manages third-generation family land. This background gives the content a strong practical context rather than making it merely conceptual.
The crawled text does not provide clear pricing, course package fees, or certificate information. The site includes a cart, checkout, and a subscription prompt for “new online courses,” but it is not currently possible to determine whether the content is paid, how purchases work, or whether PDC certification or a completion certificate is offered. Learners who need a formal certificate should verify this separately.
The main strength is that the system closely follows the classic PDC framework, combining philosophy, ecological ethics, design methods, and case studies, making it useful for building a structured understanding. The author’s extensive experience and global examples help explain the logic of site-specific design. The drawbacks are that the level of course structure is unclear, and there is no clearly defined learning path, assignment feedback, community mentoring, certificate, or pricing information. The long-form English content may also be a barrier for Chinese-speaking users.
It is best suited to permaculture beginners, PDC students, ecological farm operators, community garden practitioners, and anyone looking to strengthen their design theory foundation. If the goal is formal certification or Chinese-language teaching support, the site does not provide enough information. Access from mainland China cannot be determined from the available text, so it should be considered unknown.
