Answer:
Let's analyze the graph.
we can see that in 1995, the total area occupied was around 8 he.
Then we have a steep increase, reaching a maximum in the year 1997, where the area occupied was 20 he.
After that the area decreases abruptly and remains (varying a little from year to year) around 5he
Now we can look at the year 2006, that year the area was around 5he, ut after that we can see an almost constant decrease in the area, where each year (except from 2010 to 2011) the area decreased.
Ending in 2014 near 1 or 2 hectares.
The conclusion that we can take from this graph is that, while some years ao the area fluctuated around some values, in recent years we can see a clear decrease in the area ocuppied by the Overwintering Monarchs.
