Story 1|Restoring a Mountain Garden(Words 301—325)
On a stone terrace, a forestry team sorted fallen timber beside bags of charcoal. Each log carried the project logo, showing which branch of the reserve had supplied it. The team measured every trunk, checked each heavy bough, and protected the exposed root systems. Nearby, farmers stored hay and straw, while reed beds filtered water below a hedge of thorn. Volunteers removed weed from the grass, reopened a flower-rich meadow, and repaired the research-station lawn. They planted an olive, a young pine, and a climbing vine, then added violet, tulip, and mint around a pond designed like a coral reef.

Story 2|Balancing a Wetland Ecosystem(Words 326—350)
A single alga isolated from a sudden bloom led researchers to test an enzyme that might act as a natural catalyst. The treatment could release oxygen without increasing the rate of carbon emission, allowing plants to absorb more light and improve water circulation. Because pollution levels might exceed safe limits, the team measured nutrient uptake, every key nutrient, and the energy available in the wetland's surroundings. Their model explained the recovery mechanism and showed how wetland plants could counterbalance the effects of farm runoff. To protect fish, managers chose to preserve a quiet zone and fund long-term conservation. Fire crews learned to extinguish nearby wildfires before they could ruin nests or make young birds perish, while workers prepared to demolish an unsafe observation hut. New rules warned visitors not to infringe access regulations or undermine the plan, reducing the risk of extinction and restoring a stable migration pattern.
中文梗概: 研究人员通过监测藻类、营养吸收与能量循环寻找湿地平衡机制,同时以保护区、消防和规则降低污染及灭绝风险。
Story 3|Designing a Wildlife Study(Words 351—375)
The first trial produced a promising outcome, but its long-term impact remained uncertain because animal movement was highly seasonal. An experimental camera system worked under favorable conditions and proved both productive and effective, although a more efficient battery could save a considerable amount of field time. The reserve covered a massive valley and an immense forest, so the team compared maximal coverage with minimal disturbance to find the optimal survey design. A biologist, a zoologist, an ecologist, and a botanist reviewed each record. They identified every mammal and primate, separated each vertebrate from any reptile or amphibian, and noted whether the animal was a carnivore or herbivore.
中文梗概: 多学科团队评估实验相机的效果、效率和覆盖尺度,并按哺乳类、灵长类、脊椎类及食性对记录到的动物进行分类。
Story 4|Following an Island Population(Words 376—400)
Every creature on the island formed part of its wildlife, from the coastal fauna to the mountain flora. Individuals of one rare species travelled in a flock, while deer formed a herd and insects gathered in a swarm. At the observation deck, a throng of visitors became a noisy crowd when a large beast appeared, but the guide warned them not to treat it as a mindless brute or support cruel handling. Genetic evidence suggested that the population did not originate locally but might derive from migrants carried on storm debris. A plant stem preserved beside an ancient ancestor helped connect each modern descendant and its offspring to a distinct subgroup. Rangers adjusted what they feed captive animals and monitored how they breed, whether neighbouring groups interbreed, and whether related plants hybridize. Under favourable conditions, both populations could proliferate.
