  The strong decays of $D_1(2420)^0$, $D_2^*(2460)^0$, $D_2^*(2460)^+$,
$D_2^*(2460)^-$, $D(2550)^0$, $D_J^*(2600)^0$, $D(2740)^0$, $D_3^*(2750)^0$,
$D_3^*(2750)^+$, $D_3^*(2750)^-$, $D_J(3000)^0$, $D{_{J}^*}(3000)^0$ and
$D_2^*(3000)^0$ resonance states are analyzed in the heavy quark mass limit of
Heavy Quark Effective Theory (HQET). The individual decay rates and the
branching ratios among the strong decays determine their spin and parity. From
such states the Regge trajectories are constructed in $(J, M^2)$ and $(n_r,
M^2)$ planes and further predict the masses of higher excited states (1$^1D_2$,
1$^3D_3$, 3$^1S_0$, 3$^3S_1$, 1$^1F_3$, 1$^3F_4$, 2$^3D_3$, 3$^3P_2$ and
2$^3F_4$) lying on Regge lines by fixing their slopes and intercepts. Moreover,
the strong decay rates and the branching ratios of these higher excited states
are also examined, which can help the experimentalists to search these states
into their respective decay modes.
