By going from north to south
dN/dT = rK (K-N)/K
Here, K is carrying capacity
N = Population size
r = Intrinsic rate
dN/dT = 0.8*250 (1500-250)/1500
dN/dT = 166.66 that is equivalent to 167 animal in a year
Thus, in 2015, there would be 250 individuals and in 2016, there would be 260+167 = 417 animals.
