  We consider the extinction regime in the spatial stochastic logistic model in
$\mathbb{R}^d$ (a.k.a. Bolker--Pacala--Dieckmann--Law model of spatial
populations) using the first-order perturbation beyond the mean-field equation.
In space homogeneous case (i.e. when the density is non-spatial and the
covariance is translation invariant), we show that the perturbation converges
as time tends to infinity; that yields the first-order approximation for the
stationary density. Next, we study the critical mortality---the smallest
constant death rate which ensures the extinction of the population---as a
function of the mean-field scaling parameter $\varepsilon>0$. We find the
leading term of the asymptotic expansion (as $\varepsilon\to0$) of the critical
mortality which is apparently different for the cases $d\geq3$, $d=2$, and
$d=1$.
