A Wetland Returns: Read the News, Watch the Evidence

• ○A. The crews created a sealed pool to keep water at one level.
• ○B. The crews used planting flags to move water into separate channels.
• ○C. The crews directed water away from the basin toward the fields.
• ○D. The crews changed the drainage route so water could spread sideways.

ALDER BEND—Crews have finished the first construction stage of a project to restore a drained wetland beside the town's recreation fields.For years, a straight ditch carried water away from the site.This month, workers blocked part of that ditch and lowered a section of its bank, allowing water to spread into a shallow basin.The town will keep the recreation fields outside the restoration area.

• ○A. Plant colors were chosen to make the basin easier to film.
• ○B. Plant locations were chosen to match different moisture conditions.
• ○C. Surviving plants were separated from plants needing replacement.
• ○D. Older plants were separated from plants added more recently.

• ○A. The first scene compares two views from the same camera position.
• ○B. The third scene places blue flags in water and yellow flags on a damp edge.
• ○C. The fourth scene places the inlet and outlet jars beside each other.
• ○D. The second scene shows water moving through the remaining outlet.

• ○A. The jars were collected before water could move through the restored basin.
• ○B. Water quality is determined by how closely the jars stand together.
• ○C. The jar labels identify locations rather than the dates of construction.
• ○D. Water may contain dissolved substances that its appearance does not reveal.

The project also aims to improve habitat and help trap sediment carried by runoff.Slower-moving water can allow some suspended particles to settle.Clear-looking water, however, may still contain dissolved substances that a camera cannot reveal.Staff plan to sample water entering and leaving the basin rather than judge water quality by appearance.

• ○A. Blocked ditch and outlet → sampling jars → planting flags
• ○B. Sampling jars → blocked ditch and outlet → planting flags
• ○C. Blocked ditch and outlet → planting flags → sampling jars
• ○D. Planting flags → sampling jars → blocked ditch and outlet

• ○A. The basin stores some water temporarily, while its level changes with conditions.
• ○B. The staff will use repeated surveys to record wildlife at the restored site.
• ○C. The staff will check whether unwanted plants crowd out the planted species.
• ○D. The town intends to keep recreation fields outside the restoration area.

• ○A. They show the water's location before construction and after one storm.
• ○B. They identify wildlife surveys as a way to track use over time.
• ○C. They explain that slower water can allow suspended particles to settle.
• ○D. They define wetlands as places with water-covered or saturated ground.

• ○A. A closer view of the jar labels during the original sampling visit
• ○B. Repeated views of the heron taken during its brief appearance
• ○C. Labeled views of the same planting zones on several later visits
• ○D. A longer view of the outlet with the planting areas outside the frame

• ○A. The heron records one use of the site; later surveys will track regular use.
• ○B. The heron shows that restored wetlands attract the same wildlife each season.
• ○C. The heron records the site's water quality more directly than sampling can.
• ○D. The heron shows that planting success can be measured without later checks.

• ○A. Where did staff collect the two water samples shown together?
• ○B. Which planted species survived through the site's first full year?
• ○C. Why did workers place plants in separate moisture zones?
• ○D. What happened to part of the ditch during the construction work?
