Graph 1
What is decreasing over time in graph 1? Be specific
The percentage of forest covered by native trees is decreasing over time
Why does each tree species have 3 bars in graph 2? What do the different colors represent?
The different colors represent trees of different sizes (diameters) within the same species
What does the y-axis of graph 3 measure and what does it mean?
height reduction in tree seedlings (height loss in young wilding pines)
Which sheep stocking rate resulted in the "credibility interval" for seedling survival being 30% to 58%
2x sheep stocking
The number of wilding pines increases and the number of native trees decreases
Which diameter size of white pine tree stores the most carbon? How much carbon do they sequester?
White pine trees with diameter = 60 cm store 3.1 units of carbon
If tree seedlings have a 80% reduction in height, are they smaller than if they had a 20% reduction in height, or taller?
shorter - more reduction means they lose more of their height
Central tendency = average or median - the solid line
The title of graph 1 means that the researchers studied how the percentage of native trees covering the forest changed because of what other factor?
The percentage of native trees was affected by an invasive tree species.
Graph 2 shows how what factor changes as a tree diameter gets larger?
Carbon sequestration (storage) changes as the tree diameter gets larger
Graph 3 shows that what happens as the sheep stocking increases?
the height reduction increases as the stocking rate increases - the average tree height is shorter when there are more sheep
What does graph 4 show about the relationship between sheep stocking and seedling survival probability?
When there were more sheep, the wilding pine seedlings were less likely to survive
What percentage of the forest was covered by native species 10 years after invasion by wilding pines?
native species covered about 33% of the forest
What is the carbon sequestration rate of a 60-cm black cherry tree?
4.00 units of carbon
What sheep stocking rate resulted in a 77% reduction in height for seedlings?
When the sheep stocking rate was 6x, what was the average (central tendency) probability of survival for a wilding pine seedling?
About 10%
