On the first day, you will lead the class in defining biodiversity and discussing the importance of biodiversity for the global environment and human populations. Students will explore the natural environments and biological diversity of the Solomon Islands and discuss its global importance. Finally, the class will examine current local and global threats to biodiversity. On the second day of the lesson, the class will examine strategies and practices that are used to promote the conservation of biological diversity, using the concept of flagship species. A flagship species acts as an ambassador, or mascot, for its ecosystem. Working in small groups, students will select a plant or animal to serve as a flagship species for ecosystems in the Solomon Islands. They will then develop and present a short story to promote their selected species and explain why that species should be selected to represent the Solomon Islands. At the start of this lesson plan, you will find background information on the topic of biodiversity and its importance. This information is intended for you as the instructor, and can be presented to students in the manner of your choosing. Included in the text are suggestions for short discussion questions and activities to help you familiarize students with these ideas. Using this lesson plan, you will guide students to: Explore the biodiversity of the Solomon Islands Discuss the value of biodiversity to life in the Solomon Islands Identify threats to biodiversity and how natural systems and human populations might be affected by biodiversity loss 3 DAY 1: WHAT IS BIODIVERSITY? Times Teacher’s Activity Students’ Activity WHAT IS Introduce the concept of BIODIVERSITY? biodiversity to students. Ask 0:00-0:10 (10 Minutes) students to brainstorm examples of biodiversity in the Solomon Islands and write down their list. Brainstorm and share names of plants and animals found in the Solomon Islands. WHY IS BIODIVERSITY IMPORTANT? 0:10-0:25 (15 Minutes) Introduce the concepts of utilitarian and intrinsic value. Ask students to pick an example from their previous list of biodiversity and brainstorm its value(s). Brainstorm and share lists of values associated with species from the list of plants and animals found in the Solomon Islands. BIODIVERSITY IN THE SOLOMON ISLANDS 0:25-0:30 (5 Minutes) Define endemism as an attribute of biodiversity. Give students an overview of the levels of diversity and endemism in the Solomon Islands, and how unique the islands are in terms of global biodiversity. Refer to Appendix I for some plant and animal species endemic to the Solomon Islands. Identify species on the existing list of plants and animals that are endemic – found only on the Solomon Islands. Why does it matter if a species is endemic or not? THREATS TO Give an overview of the historical BIOLOGICAL and ongoing threats to biological DIVERSITY diversity in the Solomon Islands. 0:30-0:40 (10 Minutes) Choose examples from the existing list of plants and animals. Imagine that human activities have directly or indirectly caused the extinction of this organism. Would the Solomon Islands change in the absence of the now extinct plant or animal? 1. WHAT IS BIODIVERSITY? (10 MINUTES) Biodiversity is another way of saying “biological diversity.” It is often used to describe all the species—or groups of organisms (plants and animals) of the same kind, for example, the Solomons Flying Fox (Pteropus rayneri)1—living in a particular area. If we consider this area of interest as the entire world, then biodiversity can be summarized as all “life on earth.” Scientists use a broader definition of biodiversity, to include not only living organisms and the way that they interact with each other, but also interactions with the non-living aspects of their environment. For example, biodiversity not only includes a bird and the fish that it eats, but also the act of the bird eating the 1 Different criteria are used to determine whether organisms are of the same kind - such as whether they interbreed, or have distinguishable differences. Different scientists may prefer different criteria or concepts, for defining species, and this can affect how they count, and consequently, conserve species. 4 fish (and the fish’s interactions with its environment, such as using coral for shelter from predators). A good definition of biodiversity is: Biodiversity is the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. In other words, from the single trait of one animal (e.g., the color of a fish) to the river where it lives to the water cycle that keeps the water clean. Student Activity Write the definition of “biodiversity” on the board and ask students to brainstorm examples of biodiversity in the Solomon Islands. Be sure to give them a couple of minutes to reflect. Write down their examples on the board or a flip chart – you will return to this list later in the class period. For example, students may name fish, trees, birds, sea turtles, coral reefs, etc. Students may also be more exact, for instance listing a particular species by its common or traditional name. Encourage them to think beyond just naming individual species and consider biodiversity on a larger scale: the ecosystems where they live (rivers, coral reefs, bush), traits that make these ecosystems interesting or unique, and the many different connections within an ecosystem, between plants and animals and their environment. You may ask them questions like: - Are you remembering to think about what is beneath your feet, in the ground below? What is above you in the air? - Are there certain plants or animals you see only if another organism is present? At certain times of year? 2. WHY IS BIODIVERSITY IMPORTANT? (15 MINUTES) People depend upon biodiversity in many ways, both to satisfy basic needs like food and medicine, and to enrich our lives culturally or spiritually. Yet some people forget how fundamental biodiversity is to daily life and are unaware of the potential impact of its loss. Determining the value or worth of biodiversity is complex and often causes debate. This is largely because biodiversity means different things to different people, and its worth is a reflection of underlying human values. These values may vary dramatically among societies, within communities, and between individuals. Values are also dynamic - they change over time and vary according to specific situations. As an example, consider the perspective of rural versus urban human populations towards the forest. How might their attitudes toward the bush differ? In conservation science, the value of biodiversity is often divided into two main categories: Utilitarian (also known as instrumental, extrinsic, or use) value, and Intrinsic (also called inherent) value. 5 A living thing’s utilitarian value is determined by its use or function. Usually utilitarian value is measured in terms of its use for humans, such as for medicine, food, building material, etc. However, it can also represent the value of an organism to other living things or its ecological value: for example, pollinators, such as bees, are necessary in the reproduction process of many plants. Phytoplankton (tiny ocean-dwelling organisms, such as algae, that can photosynthesize) produce the majority of the Earth’s oxygen! In contrast, intrinsic value describes the inherent worth of an organism, independent of its value to anyone or anything else. In other words, it is the idea that all living things have a right to exist – regardless of their utilitarian value to others. Student Activity Introduce students to the concepts of “utilitarian value” and “intrinsic value,” and then ask them to look back over their previous list of biodiversity in the Solomon Islands. Pick an example from the list and then ask students to think of its value. There may be multiple types of value for one example – for instance, “trees” might have many different values, including utilitarian values like “food” or “building materials,” “shade,” or even “climbing.” Students may also propose that trees have intrinsic worth and just their existence alone is valuable. Encourage students to consider the spiritual and cultural values that each selected example might have – or even its recreational value! Repeat this exercise with several examples. If the students have not suggested intrinsic values for any of the examples, ask students to identify an example with intrinsic value. Why have they chosen that example (or not)? Do all the examples of the list have intrinsic value? Why or why not? 3. BIODIVERSITY IN THE SOLOMON ISLANDS (5 MINUTES) The Solomon Islands are known worldwide for their remarkable biodiversity. The islands contain many different ecosystems and vegetation types, such as mangrove forests, lowland forest, and montane (cloud) forests. Seagrasses and mangroves stretch across the archipelago, providing important feeding, breeding, and nesting habitat, and act as a link between terrestrial and marine ecosystems. The mangrove forests on the islands of Rennell, Shortland, Malaita, and New Georgia contain 26 different species of mangrove - nearly half of all the mangrove species in the world! Additionally, the rivers and streams of the Solomon Islands are an area of active and exciting scientific research, with new species still being described by scientists. The islands are especially famous internationally for high levels of species found only in one place in the world, or endemism. Terrestrially, the Solomon Islands have at least 69 endemic bird species, and at least half of its palms (57%) and its orchids (50%) are also found nowhere else in the world. Another well-known endemic species is the Solomon Islands skink (Corucia zebrata), the largest skink on Earth. Because of how life evolved on these islands, each island hosts different groups of species, and in many cases an island will have endemic species found on that island alone. See also Appendix I for more examples of species endemic to the Solomon Islands and found nowhere else in the world. 6 The marine environments of the Solomon Islands are also extraordinarily diverse. The Solomon Islands are a part of “the Coral Triangle,” a marine area that spans the waters of Indonesia, Malaysia, Papua New Guinea, the Philippines, and Timor-Leste and has the most diverse coral reef ecosystems in the world. Over 1,000 species of fish have been found in the Solomon Islands. In 2004, scientists recorded 279 fish species on a single dive – this is the fourth highest number of species ever recorded on a single dive! Student Activity Ask students to see if they can identify species on their biodiversity list that can be found only in the Solomon Islands, or if they can name other species or organisms that they know or think are endemic to the Solomon Islands. (See Appendix I for a partial list of species endemic to the Solomon Islands.) Why is it important if a species if endemic? Students should be encouraged to think about why they think endemism is important. Some answers may include: cultural identity and values – endemic species are often important nationally or regionally; increasing scientific knowledge (for example, endemism is important to the study of evolution, about how and why a species may only be found in one place); biodiversity – endemic species are often at risk of extinction and once lost locally, they are lost worldwide. THREATS TO BIOLOGICAL DIVERSITY (10 MINUTES) Like many ecosystems around the world, the Solomon Islands face threats to its biodiversity. Human impact has sped up the rate of extinction (when all individuals of a given species die, causing the species as a whole to disappear), starting with the initial arrival of humans about 30,000 years ago and increasing with the arrival of cats and dogs in the 16th century. Species like kukuvoju (Microgoura meeki, Choiseul Crested Pigeon) and other ground-dwelling birds evolved without mammalian predators and were thus especially vulnerable to over-harvesting by humans and their pets (not recognizing them as threats and being unable to fly away). Invasive species (or nonnative plants and animals that negatively affect ecosystems, like fire ants) threaten both aquatic and terrestrial environments, and these threats can be made worse when they are combined with changes in the environment like the increase in logging.2 Freshwater and marine fish species face problems due to overfishing, mass harvesting, competition from invasive species for food, changes in water quality from logging, and potentially runoff from industrial mining. New fishing methods (gill nets, spear fishing at night, and fishing with explosives) are putting additional pressure on fisheries because of higher levels of fish consumption and higher impacts on the ecosystem. For example, 2 See the Global Invasive Species Database for more information on invasive species and the Solomon Islands: http://www.issg.org/database/species/search.asp?sts=sss&st=sss&fr=1&sn=&rn=solomon+islands&hci=1&ei=-1&lang=EN 7 dynamite fishing destroys the habitat that would support individual fish who could replace the fish that are caught. This then reduces a fish population’s ability to replace the fish that are removed from the system. It is difficult to tell what may be the most important threats to biodiversity in the future, particularly as interest in commercial mining grows, but the greatest threat to all biological diversity in the Solomon Islands to date has probably been unsustainable logging. In response to logging restrictions in their own countries, Southeast Asian companies have come to the Solomon Islands, and there has been a rapid increase in commercial logging in the country since 1992. Logging causes increased erosion in the soil and higher levels of sediment in the water, affecting water quality, and is a major threat to freshwater and freshwater environments. Additionally, terrestrial fauna (or species living on land) are losing valuable habitat through forest conversion and loss due to logging. The International Union for Conservation of Nature (IUCN) has listed 16 plant species of the Solomon Islands as threatened (i.e., at risk of extinction), including several palm and tree species, like Burmese Rosewood (Pterocarpus indicus) and the endangered New Guinea Ebony (Diospyros insularis). Student Activity Ask students to pick an example of biodiversity from your list and discuss how their life in the Solomon Islands might be changed if it were to disappear. If students do not think their life would change, encourage them to think about how species support one another, like pollinators and plant reproduction. You may wish to revisit your earlier discussion on utilitarian and intrinsic values. Optional homework: Ask students if they can think of a plant or animal that their parents talk about that can no longer be found or one that they have noticed is less abundant than it was when they were growing up. Has the disappearance of this plant/animal impacted your life? Has it changed any other part of your environment? If so, how? If not, why not? 8 DAY 2: BIODIVERSITY CONSERVATION Times Teacher’s Activity Students’ Activity CONSERVATION OF BIODIVERSITY 0:00-0:05 (5 Minutes) Introduce conservation decisionmaking, noting that our own values of biodiversity influence how we make decisions regarding conservation. ACTIVITY: CHOOSING A FLAGSHIP SPECIES 0:05-0:40 (35 Minutes*) Divide the class into small groups. Working in small groups, Give an overview of the “flagship choose a flagship species for species” activity. the Solomon Islands. Design a short play or story to explain why your chosen species is a good ambassador for Solomon Islands ecosystems. Briefly reflect on what you have learned. ** Note: The activity described below asks students to choose a flagship species, then develop and perform short educational plays. This might not be possible if your class period is strictly limited to 40 minutes – it is better suited to a longer class period. As an alternative to a play, you could ask students to: - - - Reflect on the questions below and, in small groups, design a flag showcasing the species they have chosen. Students would then take turns presenting their flags, highlighting why they have chosen that species and its importance to the Solomon Islands. Reflect on the questions below and, in small groups, design promotional materials (an advertisement, billboard, flyer) showcasing the species they have chosen. Students would then take turns presenting their work, highlighting why they have chosen that species and its importance to the Solomon Islands. Reflect on the questions below and, individually, write a short poem on the species they have chosen and its importance to the Solomon Islands. This could also be completed as homework. CONSERVATION OF BIODIVERSITY (5 MINUTES) Why is biodiversity important? Values are central to conservation decisions, which seek to protect natural resources for the future. When we set conservation priorities, we must decide which species, populations, or ecosystems to study, monitor, manage, or conserve, and these choices depend upon what we currently value. Here are some questions we might ask: Which species/ecosystems should be protected? 9 Should we give priority to a species/ecosystem that is nationally endangered but globally common, or to a species/ecosystem that is nationally common and globally rare? Should we give priority to a species/ecosystem that is culturally and/or economically valuable? Should we value areas with greater numbers of species over those with many endemic species? There are no correct answers to these questions – the responses depend upon what the decision-makers’ value and what information is available to make these decisions. Utilitarian values are also used to justify the conservation of species or ecosystems, for example whether a particular area is valuable for recreation, logging, or fishing. In most countries, conservation efforts focus on the species listed as endangered and threatened (with the focus often on large and well-studied plants and animals). Also, people often favor “charismatic” or attractive species, such as elephants and sea turtles. Ultimately, every decision people make, consciously or not, is based on what they, as individuals, value and these are the values that will be learned by their children. II. ACTIVITY – CHOOSING A FLAGSHIP SPECIES (AT LEAST 35 MINUTES) One technique used to promote the importance of biodiversity conservation and influence decision-making is a flagship species, or a species chosen to represent a larger environmental cause or concern. Flagship species are generally chosen because of their appeal to the larger public or their symbolic value. For instance, the Giant Panda of China or the Mountain Gorilla of Central Africa are used to build support for conservation of key ecosystems where these species live. The idea is that by raising public interest in one particular species and demonstrating its role as a representative of the larger ecosystem, you can also create support conserving other biodiversity that surrounds it. Another way to think of it is that a flagship species acts as an ambassador for its ecosystem, or a mascot. If you had to choose a flagship species for the Solomon Islands, what species would you choose and why? Step 1: Split into groups Divide the class into three groups and explain that they will be selecting their own “flagship species” to support conservation in the Solomon Islands. Alternately, you can ask students to choose a flagship species for their province or island. Step 2: Choose a flagship species (5-20 minutes) You can ask groups to select a species of their choice or select from the list generated earlier in Day 1. They should think about choosing a species that they feel will represent the Solomon Islands (or their province/ island) and is important biologically and culturally. For example, they should consider the value(s) of the species – does it provide a key service to people? To the land or other animals? Or does it have a unique 10 or beautiful appearance? Perhaps it features prominently in local stories or history, or has qualities that we admire (“fierce,” “strong,” “wise,” etc.)? These are all potential reasons to choose a flagship species. Ask students to prepare answers to the following questions: - Why is this species important? - Why is it important to the Solomon Islands in particular? - Does it exist somewhere else in the world? - Does this species play an important role for humans? Examples: food, spiritual value, medicinal, protection - What role(s) does this species play in its environment? Examples: predators, scavengers, pollinators - How can this species act as a “mascot” or “ambassador” for conservation in the Solomon Islands? Step 3: Design a play (At least 15 minutes) After selecting their species, student groups will each design and perform a short educational play (at least 2-3 minutes long) demonstrating the importance of their species (and the biodiversity it represents) and why they have chosen it. Plays can be funny, dramatic, mysterious, or take any form – the only limits are your students’ creativity! Students should have at least 15 minutes to create their plays. If you want to extend the activity, students can do homework researching their species and create longer plays. Step 4: Students perform plays (At least 15 minutes) Each group should have at least 2-3 minutes to perform their play, plus 1-2 minutes to answer questions from the class about their species and why they think it’s important. Step 5. Individual Reflection Ask students to reflect on what they have learned with the following questions – this can be a homework assignment or a short class discussion. How effective do you think protecting this species will be for biodiversity as a whole? What other strategies would you use to have effective conservation of biodiversity in the Solomon Islands? 11 ACKNOWLEDGEMENTS The development of this lesson plan was led by scientists and educators at the American Museum of Natural History (AMNH), with special contributions by Kristin Douglas, Kimberley Landrigan, and Brian Weeks of the Center for Biodiversity and Conservation at AMNH.
