It is shown that trapping-electron--induced scattering can be dominant over nonlinear ion Landau damping in the saturation of short-wavelength, dispersive, trapped-electron instabilities in tokamaks. Trapped-electron-induced scattering transfers the wave energy to shorter wavelengths, where it can be dissipated by ion viscosity.
