Permaculture: an introduction

• A. Fair Share
• B. Earth Care ✓
• C. People Care
• D. Design Care

Why: The three core ethics of permaculture are Earth Care, People Care, and Fair Share. Earth Care focuses on protecting and regenerating ecosystems, soil, water, and biodiversity, recognizing that a healthy planet is the foundation for all other activity.

• A. Maximizing profit from land use for the designer
• B. Setting limits on consumption and redistributing surplus to support others and the system ✓
• C. Dividing land equally among all community members
• D. Using only native plants in every garden design

Why: Fair Share, sometimes called Return of Surplus, means consuming within limits and sharing surplus resources such as food, time, and energy. It keeps systems sustainable by preventing overuse and encouraging reinvestment in the community and the land.

• A. Use and value renewable resources and services ✓
• B. Produce no waste
• C. Obtain a yield
• D. Apply self-regulation and accept feedback

Why: The principle 'Observe and Interact' asks designers to spend time watching how a site behaves across seasons before making changes. Careful observation leads to better decisions because the designer understands sun, wind, water, and existing life patterns first.

• A. Eliminating all human-generated materials from a site
• B. Ensuring every output of one system becomes an input for another ✓
• C. Recycling only plastic and metal
• D. Reducing the number of plant species grown

Why: Produce No Waste treats waste as a resource. By designing cycles where the outputs of one element, such as kitchen scraps or animal manure, serve as inputs for another, the system reduces losses and builds closed loops similar to those found in natural ecosystems.

• A. Edges are cheaper to buy than the center of a property
• B. Boundaries between ecosystems are typically the most biologically productive and diverse zones ✓
• C. Marginal land is legally required to be left unused
• D. Edges reduce the amount of sunlight plants receive

Why: Edges, where two systems meet, such as forest and meadow or pond and land, tend to have higher diversity and productivity. Permaculture designers therefore place useful elements along boundaries and make use of land that others might overlook.

• A. To immediately identify which plants can be sold for profit
• B. To understand existing patterns of sun, water, wind, and soil so the design works with natural systems ✓
• C. To remove all existing vegetation so the designer starts with a blank slate
• D. To confirm that the site matches the designer's original plan

Why: Permaculture design begins with observing how a site actually functions, including sun paths, water flow, wind, and soil, so that the design works with these existing patterns rather than against them.

• A. A soil pH meter
• B. A rain gauge
• C. A sun and shadow map or sun chart ✓
• D. A moisture probe

Why: A sun and shadow map records how sunlight and shade move across the site through the seasons, helping designers decide where to place sun-loving plants, buildings, and heat-storing features.

• A. Because wet soil is easier to dig for planting
• B. To observe where water pools, flows, and erodes, revealing drainage patterns ✓
• C. To check whether the site is suitable for swimming
• D. Because rain removes all weeds from the ground

Why: Observing water in action after rain shows where it collects, where it runs off, and where erosion occurs, which informs swales, ponds, and other water-management decisions.

• A. Dividing the site into zones based on how frequently elements need visiting, with high-use areas placed closer to the home ✓
• B. Measuring the legal property boundaries of the land
• C. Classifying soil into official scientific categories
• D. Assigning each plant to a specific climate zone map

Why: Zone analysis arranges elements by how often they need attention: daily-use items like herbs sit in Zone 1 near the home, while rarely visited areas like woodlots sit in outer zones, saving time and energy.

• A. Counting the number of bird species overhead only
• B. Noticing which plants grow naturally, along with soil color, texture, earthworm presence, and smell ✓
• C. Measuring the temperature of the air at noon
• D. Recording the site's distance from the nearest town

Why: Indicator plants, soil texture, color, organisms like earthworms, and smell all provide clues about soil health, and these direct observations are central to permaculture site analysis.

• A. Repeatedly tilling the soil each season
• B. Adding mulch and compost to the soil surface ✓
• C. Applying synthetic nitrogen fertilizer every week
• D. Leaving bare soil exposed between crops

Why: Mulch and compost feed soil organisms, build organic matter, and improve aggregate structure, while tilling and bare soil tend to degrade it.

• A. To drain water quickly off the site
• B. To capture and slowly infiltrate rainwater across the landscape ✓
• C. To store water in sealed tanks for drinking
• D. To channel floodwater into the nearest river

Why: Swales are level ditches dug along contour lines that catch runoff and let it soak into the soil, recharging groundwater and keeping moisture available to plants.

• A. Following the steepest slope to move water downhill fast
• B. Placing features along lines of equal elevation ✓
• C. Arranging beds in straight rows aligned with property boundaries
• D. Planting only on the flattest part of the land

Why: Contour lines connect points of equal elevation; working along them slows water movement and spreads it evenly across the land instead of letting it erode the slope.

• A. Legumes such as clover or beans ✓
• B. Cacti and succulents
• C. Pine trees with dense needle litter
• D. Plants that grow only in shade

Why: Legumes host rhizobia bacteria in root nodules that convert atmospheric nitrogen into forms plants can use, enriching the soil for neighboring plants.

• A. It prevents rain from ever reaching the soil
• B. It reduces evaporation, erosion, and temperature swings while supporting soil life ✓
• C. It makes the soil compact and easier to walk on
• D. It stops all microbial activity in the soil

Why: Ground cover shades the soil, slows evaporation, protects it from rain impact and erosion, and provides food and habitat for soil organisms.

• A. A single species planted in dense rows to maximize yield
• B. A group of plants that support one another around a central 'hub' plant, providing functions such as nitrogen fixing, pest control, and ground cover ✓
• C. A professional association of permaculture designers
• D. A type of irrigation system that waters plants from below

Why: A plant guild is a mutually beneficial assemblage of plants, typically built around a central tree or shrub, where each member fills a specific role such as nitrogen fixing, attracting beneficial insects, or suppressing weeds.

• A. Sunflower
• B. Carrot
• C. White clover ✓
• D. Garlic

Why: White clover is a legume that hosts nitrogen-fixing bacteria in its root nodules, converting atmospheric nitrogen into a form plants can use, which benefits neighboring plants like fruit trees.

• A. To produce the largest possible harvest for the gardener
• B. To draw up nutrients from deep in the soil and make them available to other plants through leaf litter and biomass ✓
• C. To shade out all competing vegetation
• D. To repel all insects from the garden

Why: Dynamic accumulators, such as comfrey and yarrow, have deep root systems that mine nutrients, and when their leaves are cut and dropped as mulch, those nutrients become available to shallower-rooted companion plants.

• A. It competes with the tree for all available water
• B. It suppresses weeds, retains soil moisture, and can attract beneficial insects ✓
• C. It must be removed each season to prevent disease
• D. It prevents any pollination from occurring

Why: Living ground covers protect soil from erosion and drying, outcompete weeds, and often provide habitat or flowers for beneficial insects, all of which support the central fruit tree.

• A. Diverse plantings make maintenance more complicated and therefore more profitable
• B. Diverse plantings reduce the risk of total failure from a single pest or disease and create more stable, self-regulating systems ✓
• C. Diversity is only aesthetically pleasing and has no functional value
• D. Diverse plants always grow to the same height, simplifying harvest

Why: A variety of species creates resilience: if one plant is hit by a pest or disease, others continue to thrive, and a range of plant functions and relationships helps the system regulate itself naturally.

• A. They produce large quantities of milk for household use
• B. They consume pests and weed seeds while fertilizing the soil with manure ✓
• C. They prevent all soil erosion by digging deep root channels
• D. They replace the need for any compost or mulch materials

Why: Chickens scratch and eat insects, slugs, and weed seeds while depositing nitrogen-rich manure, making them a useful multifunctional element in permaculture systems.

• A. Each animal should serve only one purpose to simplify management
• B. Animals should be housed in the highest elevation of the site
• C. Each element should provide multiple yields or services, such as eggs, fertilizer, and pest control ✓
• D. Animals should be kept in separate zones with no interaction with plants

Why: Stacking functions means designing so that each element supplies several benefits, which is a core permaculture principle for efficient, resilient systems.

• A. Ducks are kept in dry cages away from water to avoid contamination
• B. Ducks feed on pests and snails in the water while their waste fertilizes the crop ✓
• C. Ducks are used only for pulling weeds from dry upland beds
• D. Ducks are removed before planting to avoid trampling seedlings

Why: Ducks in rice paddies eat snails, insects, and weeds while their droppings supply nutrients, reducing the need for pesticides and synthetic fertilizers.

• A. To transport eggs more easily to market
• B. To allow birds to graze and fertilize different areas of a plot without overgrazing any single spot ✓
• C. To keep birds permanently fenced in one location for security
• D. To prevent birds from ever touching the ground

Why: A movable pen lets chickens work over one area at a time, distributing manure evenly and allowing vegetation to recover, which prevents overgrazing and soil damage.

• A. Animal numbers should be matched to the carrying capacity of the land and available feed ✓
• B. Animals should always be given unlimited access to every planted area
• C. Livestock should be kept at the maximum density possible to maximize output
• D. Animal waste should be removed from the site entirely and never reused

Why: Matching stocking rates to the land's carrying capacity prevents overgrazing, soil compaction, and nutrient imbalances, keeping the system productive and sustainable.

• A. To satisfy local permitting requirements before construction begins
• B. To understand seasonal patterns of sun, wind, water, and wildlife so that design decisions fit the site
• C. To determine the exact market price of the land for resale
• D. To eliminate the need for any future maintenance

• A. Use and value renewable resources and services
• B. Produce no waste
• C. Obtain a yield
• D. Integrate rather than segregate

• A. To maximize shade during the hottest part of summer
• B. To capture the greatest amount of winter sunlight and heat
• C. To make it easier for prevailing winds to blow debris away
• D. To avoid any need for ventilation

• A. It is always the most advanced and expensive option available
• B. It is small-scale, locally repairable, and suited to the needs and resources of the community using it
• C. It requires imported parts and specialized training for every repair
• D. It is designed to be replaced rather than maintained

• A. Piling building materials as high as possible to save ground space
• B. Designing each element, such as a water tank, to serve multiple purposes like fire safety, irrigation, and thermal mass
• C. Installing multiple energy systems that each produce the same single output
• D. Storing harvested energy in one large centralized battery bank

• A. To regulate the sale of organic produce within a community
• B. To group plants and animals that mutually support one another in a shared space ✓
• C. To organize volunteer labor schedules on a farm
• D. To certify land as chemical-free for commercial markets

Why: A guild is a cluster of plants (and sometimes animals) that benefit each other, such as nitrogen-fixing legumes supporting heavy feeders, illustrating permaculture's emphasis on relationships and mutual support in design.

• A. Growing only crops that can be sold at the highest market price
• B. Ensuring the system produces something useful, such as food, materials, or energy, that meets human needs ✓
• C. Maximizing production of a single crop for export
• D. Avoiding any harvest in the first five years of a system

Why: 'Obtain a yield' is one of the core permaculture ethics/principles, emphasizing that designed systems should provide tangible outputs that support the people who maintain them, not only ecological functions.

• A. Dependence on external supply chains for essential needs like food, energy, and materials ✓
• B. The number of residents who participate in community decision-making
• C. Biodiversity within local ecosystems
• D. The use of renewable energy sources

Why: Resilient communities reduce vulnerability to distant shocks by producing more of what they need locally, so disruptions in global supply chains have less impact on daily life.

• A. A savings account that pays interest on local currency
• B. A system where members exchange services by the hour, with each hour of help earning an equal credit regardless of the skill ✓
• C. A government program that funds long-term infrastructure projects
• D. A calendar used to schedule harvest and planting seasons

Why: Time banks operate on reciprocal service exchange, valuing everyone's time equally, which builds social capital and local economic connections outside conventional money systems.

• A. Edges are cheaper to fence and maintain than open land
• B. Boundary zones where two ecosystems meet tend to be highly productive and diverse ✓
• C. Edges prevent water from flowing into neighboring properties
• D. Edges are required by law to separate agricultural zones

Why: Edge effects create rich habitats where different ecosystems overlap, increasing biodiversity and productivity, so permaculture designs deliberately multiply and use edges.
